Combined with the geotechnical engineering back-analysis theory, the displacement back-analysis method, which is based on the spatial mutual deformation theory, for deep foundation pit is also built up.
It is helpful to solve these problems by combining Genetic Algorithm with back-analysis method, and has great significance to Geotechnical numerical method research and the monitor work.
The resistance to shearing of rock mass is the stochastic variable controlled by many factors, so the authors put forwards a dynamic analysis method for determining the resistance to shearing of slipping plane of rock mass slope, and analyzed the practicability of the method.
The result showed that the dynamic analysis method is effective in practice to determining the resistance to shearing of slipping plane of rock mass slope.
Using this new back analysis method, a real engineering example of one underground coal mine roadway is used to verify the computing ability of the algorithm to real problems.
