Introduction In soil mechanics and various civil engineering construction work, as far as soil stability and foundation bearing capacity calculation analysis is concerned, shear strength parameters (internal friction angle and cohesion of soil) have a vital significance [1].
In addition, in the direct shear tests specimen deformation is in the plane strain state, which is closer with the deformation of many practical engineering [3, 4].
These equations have certain reference value of the engineering practice or scientific research for the future.

In actual engineering, the static load test often failed to reach the limit load that is not conducive to give full play to the bearing capacity of pile, due to test pile cost, counterforce device and other factors.

With the development of economy,the development of the civil engineering construction is also quick,all kinds of building structures have sprung up,the concrete and steel is the construction of the main engineering materials,every year,under the effect of various environmental factors, only our country concrete consumption is more than 1 billion cubic meters.With the passage of time,the concrete of reinforced concrete structure is corroded,the reinforced is rusted,the bearing capacity drops;Because of improper designs or constructions,there are some quality problems in some of the newly built or under construction engineering.Some other engineering,because the function changes,the load bearing increases etc.These reasons have certain effects on the structure of the safety and durability.In order to ensure the normal use of buildings,improving the safety and durability of buildings,the existing buildings need to be repaired,reinforced and transformed.Especially in some high-rise building
