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.

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].

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.

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.
