Abstract: Consolidation of dredged clays with a system of horizontal and vertical drains is considered. Horizontal drains in the system are made of sand layers, while vertical drains are plastic vertical drains (PVD). Laboratory model tests are performed to study the rapid consolidation behavior of layered clay-sand and clay with PVD. Special cares are given to settlement and the drainage rate of dredged clays with radial and vertical drain system. Numerical analysis is also used to identify the stability time of consolidation, and to verify which method is better suitable for handling large-scale dredged clays.

Abstract: The Qingdao Jiaozhou Bay Subsea Tunnel is the main important straitcrossing road linking the main city and complement city. The tunnel is about 7.8km long with six two-way lanes, which about 3.95km in sea area. The maximum waterdepth of tunnel in Jiaozhou bay is 42m, and the deepest point of crown to the sea-level is 78m. The land section is dominated by grantie, and the sea section is composited of volcanics and sub volcanics , in which the minning method was used. Combining with the layout and technical standard of Qingdao Jiaozhou bay subsea tunnel, this paper gave the detailed introduction of tunnel construction condition, construction scale, technical standards, plane alignment, vertical section selection, and construction technology.

Abstract: China's construction sector with foreign research results, the promotion of pro-urban settlements, and launched a multi neighborhood exploration. A lot of researches studied how to increase the neighbors’ intercourses in town residential quarters. For a long time, some representative theories were regarded as the criterions directing or evaluating the design of public space for residents’ intercourses in domestic urban residential quarters. Post occupancy evaluation was a significant part of the perfect design process. In this paper, surrounding the town neighbors’ intercourses, a lot of serious and systemic investigations were done in Kunming, and in addition some evaluations and self questionings were done on these theories.

Abstract: Regional earthquake disaster macro risk assessment model can be devided into two parts:economic losses and casualities. through the compare of domestic earthquake disaster as-sessment model,the existing model evaluation index is sole,and it can not reflect the differences of urban earthquake disaster in the area,according to this we built the regional seismic disaster evaluation index system, and use the PCA method to analyze the index,and get the weights of each index,further to build the regional seismic disaster economic loss evaluation index system effectde by multiple in-dex.Take the previous data between 1996 to 2009 as an example to analyze,compare the reckoning and the existing model evaluate results,and check the effectiveness and feasibility of the model.

Abstract: “Zhuangkuo” is a unique type of residence in Qinghai. It is characterized by local materials, simple structure, and convenient construction. Also, it is adapted to the natural environment. Based on a field study, this paper addresses how to inherit the ecological wisdom of this type of residence construction. Firstly, find out differences of architectural characteristics under multi-cultural. Secondly, point out the four main problems of Hehuang residence building under the background of New Rural Construction. Thirdly, explore the ecological wisdom of “Zhuangkuo” residence construction. In addition, summarize construction countermeasures and principles for innovation of Hehuang residence; propose new residential design carrying forward Hehuang architectural culture. The purpose is to provide necessary guidance and reference for inheritance and innovation of Hehuang vernacular residence.

Abstract: The way of “building high hathpaces” occupies a unique position in traditional Chinese architecture. According to the research, the ancient hathpace can not only increase the volume, raise the building height, make the buildings look more magnificent, but also help ascend for look far and widen your horizon, meanwhile, be beneficial to damp-proofing and ventilation for the hathpace itself. This is the thousands of years’ intelligence gathering of Chinese traditional architecture. In the design of “Hathpace of Stone Drum Pavilion in Baoji”, the designers take “inheriting Chinese architectural and cultural heritage” as its aim, use modern aesthetic view to elaborate the measurement and proportion, consequently, surpass the boundary of age and style, and refine the historical and cultural quintessence by innovating and developing which is wrapped up in traditional architecture. Meanwhile, material is the basic quality of architecture. The culture differences in the building of various nationalities and times came on materials. So, the using of stone can increase historical culture and feature of urban texture for “building high hathpaces”. A new approach to formal language, contemporary materials, and building technology will make “Hathpace of Stone Drum Pavilion in Baoji” become information carrier of traditional culture, communication platform between traditional building Stone Drum Pavilion and modern city, and unique building cultural phenomenon for the city of Baoji who will retain its graceful bearing and display the culture in Chou-Qin Dynasties, moreover, provide a new way of thinking for how to inherit the culture of traditional architecture.

Abstract: This paper discusses the relationship of the regional characteristics of architecture based on historical context and the characteristics of city, summarizes the response to the losing characteristics of regional architecture and the inheritance of the characteristics in the modern conditions, to give help on the protection of the regional characteristics of architecture, the city characteristics and historical context.

Abstract: Evaluation of urban system planning is to build its index system to evaluate the results of planning. First, from scale level, functional structure, spatial structure, network organizations, social development, and environment assessment, these 6 major -level evaluation systems separate into 9 secondary indicator issues and 33 tertiary evaluation indicators. After that, give each indicator a specific weight by AHP and linear algebra knowledge, then build the system of evaluation indicator for urban.

Abstract: Analyses the types and characters of the local architecture in the south of Shaanxi Province.Unscrambles the producing process and forming reason from the view of sociology.Uncovers the information existed in buildings.Spreads research method and scope to provide theoretical and practical foundations for the reconstruction and creation of architectural culture.

Abstract: In view of concrete structure of dam plant elbows section is complex and strong external constraints, the study of concrete temperature and stress during construction should be carried out by computer simulation. A case of plant elbow section of a sluice dam project is presented where the 3D FEM simulation of instability thermal field and stress field of the concrete structure is adopted after building the 3D finite element model, and the changes and distribution characteristics of temperature and stress during whole process of construction is obtained. The results show that, under the complex constraints condition, the concrete of plant elbow section has greater tensile stress, it can lead to structural cracking, and it is necessary to take appropriate temperature control measures.
