This kind of rock mass were distributed widely in the rock engineering, such as the underground engineering of hydroelectric power station, the slope engineering and the tunnel.
The engineering experience showed that the failure of rock engineering was for the propagation and coalescence of the crack which was under the environment agency.

Medium to long term engineering properties and performance of high-strength Geopolymers for structural applications Kwesi Sagoe–Crentsil, Trevor Brown and Shiqin Yan CSIRO Materials Science and Engineering PO Box 56, Highett, Victoria 3190, Australia Kwesi.Sagoe-Crentsil@csiro.au Keywords: Geopolymer, fly ash, permeability, performance, concrete Abstract.
The medium to long term engineering performance of high-strength geopolymer concrete systems are largely dependent on fluid ingress and the transport phenomena that govern permeability of structural members exposed to aggressive environments.
The Paper examines global implications of increased permeability and key durability parameters such as chloride diffusion, carbonation rates and steel reinforcement corrosion on long-term engineering and durability performance.
Introduction The durability and long-term engineering performance of ordinary Portland cement(OPC) concrete can be normally assessed by measurement of fluid transport parameters such as permeability and gas diffusion[1,2].

Method of high-precision calculation on the linear parameters for the stay-cable of the cable-stayed bridge Xi Li, Tingting Cai School of civil Engineering & Architecture, Chongqing Jiaotong University, Chongqing 400074, China lixi514@126.com Keywords: stay-cable, parameter, high-precision, method of calculate, single variable solve Abstract.
From the cable-stayed the basic linetype equations,the cable-stayed parameter of engineering application value are derived.
But these methods are quite complex, and they were not applicable for the engineering application because the computer hadn’t been universally used.
Though this method can meet the requirements of some engineering applications, its scope of application is after all limited.
This is characterized by high calculation accuracy and convenient use, and this provides a new method for engineering design.

Durability Experimental Method of RC Components Strengthened with FRP in Hot-Wet Environment Hao Zhou1,a*, Peiyan Huang1,2,b*, Guang Qin1, Demin Wei1 1 School of Civil Engineering and Transportation, South China University of Technology, Guangzhou, China; 2 State Key Laboratory of Subtropical Building Science, South China University of Technology, Guangzhou, China ahaovic@qq.com, bpyhuang@scut.edu.cn Keywords: environmental fatigue; durability; experimental method; coupling/interaction; fibre reinforced polymer (FRP) Abstract.
Introduction With the extensive application of strengthening technology using fibre reinforced polymer (FRP) for reinforced concrete (RC) structures, durability of the structures strengthened with FRP increasingly attracted researchers’ attention [1-3] and became one of the most concerned engineering problems.
It should be noted that dimensions of the specimens above were referenced to the recommendations of the Japanese Society of Civil Engineering and determined according to test conditions of this project team.

Introduction The soil in Yellow River flooded area of Eastern Henan in center China is a kind of specific soil, soft and powdery when it is dry, high underground water level, large moisture content, low load-carrying capacity, hard to compact, easy to deform after vibration particles moving, bad engineering properties.
Aiming to silty soil of the Yellow River flooded area, the influence of polypropylene fiber on soil stabilization with cement was studied, which provides good references to engineering practices.
Experiment Design In line with the relevant Chinese regulations of Test Methods of Materials Stabilized with Inorganic Binders for Highway Engineering (JTG E51-2009), test blocks were made with a dimension of Φ 50 × 50 mm.

In this paper, based on the author of many years engineering practice, analyzes and discusses the common problem in the application of high strength static pressure concrete pipe pile.
Fully recognized and respected by the civil engineering.
Under the condition of this may occur following phenomenon and accidents: ① In the process of through hard interlayer Pile body concrete may produce fatigue failure. ② Some pile can enter hard interlayer others may can't, this condition cause the Pile bearing layer and pile length difference at the some caps. ③ It’s difficult to accuracy estimate the actual length of pile, easy to cause send pile  too long or too deep longer as the result of pile need breaking,  deeper pile need  filling , so lead to the engineering cost increase.
Both consider the quality and safety of pile foundation engineering at some time need to consider economic factors.
Conclusions The pile foundation engineering is one of the geotechnical engineering technologies which have the feature of high experiential and regional.
