Disturbed state concept (DSC) was later used to simulate a variety of mechanical behavior of engineering materials [ 1-3 ] .
In the disturbed state concept , most engineering materials , such as soil, rock, metal, alloy and so is considered by the two states , namely a relatively intact(Relative Intact, abbreviated as RI) and full adjustment of status (Fully Adjusted, abbreviated FA).

The Research on Lunar Soil Simulant Production System Li Man, Tong Jingyu, Wang Zhihao, Bai Yu, Tian Dongbo, Wang Bin Science and Technology on Reliability and Environmental Engineering Laboratory; Beijing Institute of Spacecrafts Environment Engineering (BISEE), China li-man8319@163.com Keywords: lunar soil simulant, production system, rough machining equipment, pre-prepare equipment, Moon exploration Abstract:Because the lunar soil is rarely, lunar soil simulant plays an important part in lunar exploration, development and utilization of lunar resources, to establish a lunar base research work.
The most widely used lunar soil simulant in engineering research is JSC-1 developed by in the United States, which is a kind of glass-rich basaltic ash which approximates the chemical composition, mineralogy, particle size distribution, and engineering properties of lunar mare soil.
Through the rough machining equipment, fine machining equipment, air classification equipment, the input material will be processed to lunar soil simulant into 17 levels and then through the grading, mixing, pre-preparing to meet the engineering requirements of the final lunar soil simulant.
Through the rough machining equipment, fine machining equipment, air classification equipment, the raw material will be processed as 17-level lunar soil simulant particles with different sizes, and then through the grading, mixing, pre-preparing to satisfy the various requirements of scientific and engineering investigations.

Experimental Research on Concrete Shrinkage and Creep for Main Girder of Sutong Continuous Rigid-Frame Bridge Yuntao Zhang 1, a 1 School of Civil Engineering, Anhui University of Architecture，Hefei 230022, PR China ajgxyzyt@sina.com Keywords: high performance concrete (HPC), reinforced concrete (RC), shrinkage, creep.
If the reinforcement ratio is low, reinforcement exerts less influence on creep and shrinkage, and the influence of reinforcement can be neglected in engineering application.
When the reinforcement ratio is low, this exerts less effect on shrinkage and creep, so RC can be treated with plain concrete in engineering applications.

The hydraulic permeability performance of geosynthetics is an important functional technical index in the field of engineering application.
Introduction Geotextile is one kind of the geosynthetics used in civil engineering, and it also a kind of textile material, including knitted geotextile, woven geotextile, nonwoven geotextiles and composite geotextiles.
Geotextile’s main functions have engineering reinforcement, filtration, isolation and drainage, they are used for various projects of water conservancy, highway, railway, and garbage landfill[1].
The pore size characteristics of nonwoven geotextile can be designed through the production process, for instant, selecting fiber diameter, web forming, consolidation. we can design and product nonwoven geotextile which are different types, different specifications, according to different engineering need, and ensure to suit for different soil and water conditions.
Experimental and Result 2.1 Compression performance When geotextile uses in engineering applications, it is always combined with soil, and it will inevitably be pressure from soil.
