In the natural environment , engineering and equipment, there are many physical phenomena which are described by diffusion equations (group), such as the diffusion of gases, liquid permeability, heat conduction, fully developed channel flow and impurity in semiconductor material.
Due to the complexity of physics, their exact solutions are often not easy to obtain, so there is undoubtedly a very important theoretical significance and engineering application value in study of the numerical methods.

Introduction Currently, Engineering and academic circles have different views on the function of fiber in concrete, Fiber only plays the role of the crack, the mechanics performance index no effect，others think that appropriate fiber dosage can improve compressive and bending and other performance.
More and more engineering use polypropylene concrete can improve the concrete cracking performance; at the same time improve the jet concrete one-time injection thickness.
All specimens are mortar mixer mixing, in order to more accord with actual engineering needs, using manual slow mixing mode.

Stability analysis of unsaturated expansive soil slope covered by geo-membrane ZHANG Hong-yu1,a, CHEN Jiang-hu2,b, WU Wen-qing3,c, WU Jun-hua2,d 1 Nanchang Highway Survey and Design Institute, Nanchang 330006, China; 2College of Civil Engineering and Architecture, Nanchang Hangkong University, Nanchang 330063, China; 3Jiangxi Transportation Consulting Corporation, Nanchang 330008, China a1619704400@qq.com, b490901533@qq.com, c1619704400@qq.com, dwjh0796@126.com Key word: expansive soil; rainfall and evaporation; geo-membrane; hole Abstract.
A series of engineering projects show that the cracks caused by rainfall and evaporation drying-wetting cycles are the key factor of the expansive soil slope instability.
In practical engineering, we cannot guarantee the geo-membrane to completely cover the slope, which is affected by the construction; the material properties lead to geo-membrane surface appear holes, so the essence of function is cut down.
