Abstract: The paper studied characteristic of the morphology, substance and formation mechanism of Suo Duoxi deposit body in the Su Walong hydropower station reservoir area, focused on analysis of substance composition and formation at front area of deposit body (zoneII) and finally inferred the geological formation process and reached the formation mechanism . The results show that the block stones are main part of material of Suo Duoxi deposit and sandwiches gravel soils, but it is different from other four zones that the zone II takes gravel with less viscous as the skeleton and mixed up with uneven sizes and irregularly shape stones. The forming reason of deposit is the landslides at left bank of Jinsha River and rockfall of the steep mountain back of the deposit body on the right back with the effect of weathering, rainfall and glacial erosion and so on. Geological formation process of deposit determined the geomorphic features, but also changed paleocurrent of Jinsha River.

Abstract: The design of ground motion, including the response spectrum design and seismic wave design, is one of the important parameters for aseismic design of building structures. Consequently, the reasonable design of ground motion has a critical influence on the aseismic design of building structures. Given the importance of high-rise buildings, site survey data are generally in great detail. In this case, making full use of the data and reasonably designing response spectra and seismic design are more appropriate to the characteristics of specific sites of high-rise buildings than determining seismic input based on a simplified method and limited data.

Abstract: In modern buildings, with the continuous development of material science and building technology, the decorative manifestations of traditional building materials are emancipated from conventional restrictions. Supported by new processing techniques and ideas, they are endowed with new interpretations. Besides, many forceful manifestation techniques are thus formed. In particular, in some buildings dotted with intensively regional characteristics, by combining local emotional traditional materials and modern technology, the continuity of traditional materials and technology is highlighted in modern architectural structures. The continuity not only grants traditional materials with modern and artistic decorative functions, but also intensively demonstrates traditional emotions of modern buildings by combining different traditional materials’ properties and new materials, adopting their advantages and avoiding the deficiencies.

Abstract: Impressed current cathodic protection is an international generally accepted and effective protection method of concrete is adopted in seawater cooling intake & outfall structures in Zawal port, Kingdom of Saudi Arabia. Total protected concrete area is about 27000m2, including diaphragm walls, edge beams, all walls (main wall and cross wall), floor slab, top slab and wing walls. This project is extensive, changed-constructed and the operating environment is severe. The successful implementation of this project has certain significance in relative projects in the industry.

Abstract: In order to determine the best load combination and the safety factor of concrete section, contact pressure of the three dangerous sections of the secondary lining has been measured. By numerical simulation of FEM, load structure model has been created and the measured pressure has been exerted, then internal forces of each dangerous section were calculated out. Thus the most unfavourable load of each section was determined. Using statistical software, a series of load combination and the best load combination were acquired. As the result indicates, when the horizontal load and vertical load are 0.5 MPa, the safety factor of concrete section is the maximum and the load combination is the best one. It is reliable using the measure in the site with indoor numerical simulation of FEM to determine the best load combination of the secondary lining and the factor of concrete section.

Abstract: Considering the variable-permeability effect of non-Darcy flow in low-permeability reservoirs, this work set up a two-dimensional model with boundaries. The implicit finite difference algorithm was employed to solve the well test model, and typical curves in log-log scale by considering the effects of variable-permeability and non-Darcy flow were obtained. The results show that, in reservoirs with impermeable boundary, the upturned part of the pressure derivative curve caused by boundary effect will be covered by that of non-Darcy effect, indicating boundary effect is postponed to appear. The more of the non-Darcy effects result in less obvious upturn of the typical curves. The upturn of typical curves and the effect of boundary are enhanced by increasing the numbers of impermeable boundaries or by decreasing the distance from the well to the boundary.

Abstract: 1# bridge traffic engineering of LiangHeKou hydropower station is located in ganzi region in sichuan province. The altitude of main construction areas lies above the 2700m, perennial mean temperature ranges from-4.9 – 7.9°C,extreme low temperature reach-42.9°C,the temperature difference between day and night,which may adversely affect the execution of the precast concrete and cable erection. Based on the fully and deeply analyse and optimal approaches, We solved several key engineering challenges in precast arch box construction, and also provided valuable experiences for similar projects.

Abstract: As a new researching subject, building skin has attracted more concern from people and people also put more and more attention to the constructing industry at the same time. This paper stated on the basis of information dissemination and took it as the researching angle, which is based on information dissemination in architectural surface design perspectives as the starting point,so as to explore the building surface information of the impact on the audience, analyzing the information communication designing architectural concepts. Moreover, it make the design concept of building surface with the psychology of the audience.

Abstract: Architecture means the living environment by man and for man. The development of the traditional vernacular architecture of the Han nationality in Lingnan implies the principles of adaptability. The contents of adaptability can be divided into three aspects: natural adaptability, social adaptability and human adaptability. The natural adaptability of the Han's vernacular architecture in Lingnan means buildings should adapt themselves to natural circumstances like climate and geographical conditions; its social adaptability means buildings should suit the needs of economy, politics, religions, customs and other social respects; and its human adaptability means buildings should be suited to human conditions such as emotion, temperament, aspiration and so on. All the developments and changes of the Han's vernacular architecture in Lingnan are based on the natural adaptability, pushed forward by the social adaptability and always to the human adaptability.

Abstract: In order to conduct the numerical simulation of rock and soil slope strengthened by the micro-pile with reinforced bar, FEM strength reduction is combined with the program of FLAC which possesses the function of analyzing tensile and shear failure. The micro-pile is under plastic state due to its mechanic features. Solid element and ideal elastic-plastic constitutive model of Mohr-Coulomb are applied as the rock and soil mass and pile. The calculation model can work out the safety factor of slope, the dynamic changing process of pile deformation and failure, the failure mode of slope after strengthened by micro-pile. Then the structural element of pile is used to simulate piles, which can obtain the bending moment and shear force. The beam element is used to simulate the coupling beam. So the layout principle of inner force before the failure can be calculated.
