The results have practical significances in the analysis of engineering problems.
Introduction Cavity expansion theory has been applied to several practical problems in geotechnical engineering such as the interpretation of pressuremeter tests and the installation of driven piles.
Vesic's cavity expansion theory has been used widely in practical engineering.
The analysis may be very useful for the determination of pore pressure set up by driving piles into cohesive soils and the numerical results have practical significances in analyzing the engineering problems.

Introduction The most common cracks exists in the concrete engineering was shrinkage crack under restrictions of concrete contraction deformation and stressed cracks caused by loading; for cracks which caused by loading exist in all kinds of reinforced concrete specimens, the crack width was usually controlled by reinforcement to the allowable width range[1].
The fracture spacing phenomenon of reinforced concrete structure involved in materials science, Engineering science and many other research fields, it was mechanics phenomenon and science problem.
Therefore, materials scientists and engineering scholars were pay more attention on the fracture spacing problems, specially, more research work were developed aboard.
