Under normal circumstances, the roof of energy-saving insulation achieved through laying low capacity, thermal conductivity, low water absorption and certain hardness, thermal insulation material between the waterproof layer and roofing. 
This paper aims to conduct academic exchanges and communication with industry professionals, and also hopes that more researchers would involved in the study of this subject, to protect the current construction works of modern and contemporary development, providing the theoretical support.

professional wind load calculation method.
The incident potential is: （2） Where is acceleration of gravity; is amplitude of wave; is wave number; is water depth; is wave direction.
（3） This paper adopted heave plate of Spar platform in deep water in order to increase added mass and damping.
Then large size water-entrapment plate is designed to reduce heave motion of wind power system.

All these put forward higher professional requirements for the designers at present and in the future.
The new paint developed with flip-flop phenomenon with the use of nano-materials, the anti-bacterial and mildew resistant paint using nanometer material self-cleaning function, PPR water supply pipe, conductive coating with conductive function using nano-materials, UV shielding function with use of nano-materials can greatly improve the aging of yellowing resistance properties of PVC steel doors and windows, and can greatly improve the strength of plastic pipes using nanometer materials.
Li Ying studied the effect of nano SiO2 and silica fume on cement paste with water demand.
Research shows that when the nanometer SiO2 content reaches 8% of the amount of cement, water demand of cement paste increases by one time.
When the both are added and SiO2 manometer is l% and silica fume is 9%, water demand is not doubled, and the interactions can be both very obvious.

This system can be used with the existing professional wire-cutting equipment.
Extract water in surface.
After being filtered, rinse solid with water till PH neutral.

Responsible for daily work, monitoring center conducts professional analysis, proposes safe evaluations, timely finds the hidden troubles and kinds of non-standard construction behaviors on construction site, and then submits them to management division for its decision making.
Expert group provides professional advices for management division to handle risky situations and accidents in case of big dangers and major engineering accidents.
After taking vacuum wells to lower water on Sep. 25, the inclination deformation gradually stopped (no excavation conducted).

Similarly, for all simulation, physical properties of the droplet liquid (water) were: initial temperature (285K), density (998.2kg/m³), vaporization temperature (273K), thermal conductivity (0.6W/mK), with the gravitational constant of 9.8m/s².

The tunnel buried depth rangefrom 30mto 72m,tunnel surrounding rock is almost fullto strong weathering basalt, structure ofrock mass mainly as the gravel structure, full of weak interlayer; Groundwater types are mainly of bedrock fissure water, surrounding rock integrity is poor, weak self-stabilityof surrounding rock, tunnel is prone to collapse.
Application of ABAQUS in tunnel engineeringhas incomparable advantages,but still has certain defects;Forinstances, in one hand, if the parts of grid coupling condition is bad, the calculation maybe can’t finish; On the other hand, whena tunnel model is too complex to set up, the other good pre-processing software is needed.In general, under the joint efforts of the professionals, application on ABABUS in tunnel engineering has a very bright future.

And water infiltrating from tiny cracks accelerates the aging process of asphalt because of greater erosion under dynamic pressure.

Study on the environmental protection management system at ports in China Changbing Liu 1, a, Yu Lin 1,b and Wei Huang 1,c 1Tianjin Research Institute for Water Transport Engineering, Laboratory of Environmental Protection in Water Transport Engineering, Tianjin 300456, China atkyhbzx@163.com, bLinyu_1973@sina.com, cfenzhen1@163.com Key words: port project; environmental protection management system; China Abstract.
Gupta et al. [3] suggested that pollution problems caused by port activities can be categorized as follows: 1) Coastal habitats may be destroyed due to the port construction and land reclamation. 2) Unregulated engineering activities during the port construction may threaten the marine ecological environment. 3) The surface water quality may deteriorate during both the construction and operation phases. 4) The discharge and leakage of various types of wastewater, waste gas, dust, noise and litter production from loading and unloading as well as transport during the port operation. 5) Human and environment health may be affected by contamination of coastal water due to urban effluent discharge. 6) Oil pollution is one of the major environmental hazards resulting from port/harbour and shipping operations.
It’s difficulty for port unites alone to spend a lot of money which is used in the construction and operate maintaining of environmental protecting facilities, so both the limited found and environmental protection infrastructure did not get effective use. 2) The duties of the environmental protection agencies are indeterminate and lead to inefficiency in their works. 3) The fulltime staff are few and poor professional qualities. 4) The environmental management works do not combine with the whole process of the production management and only considered to serve for the production management. 5) The model and method of environmental protection management are backward and not suitable for the demands of the present situation. 6) The propaganda for the important of the port environmental protection works is still not deep enough.
