Prediction and control of ground deformation and displacement due to large slurry shield tunneling based on stochastic medium theory

The adaptability of random medium theory is discussed in estimating surface movement and deformation caused by excavation of urban tunnel and underground space.

Stochastic Medium Method(SMM) and Peck Method are widely used in the field of ground movement caused by urban soft ground tunneling in China.

Verification of the drawing theory in the random medium;

Study of prediction method in random medium theory for combined body deformation of open pit slope and hillside;

Propagation and localization of plane waves in two-dimensional homogeneous and isotropic random medium;

Using stochastic medium model in surface movements of self-weight stress mining have been made great successful .

In this paper the theory of stochastic medium widely used in mining industry is introduced into the calculation of surface and soil mass movements and deformation due to foundation pit excavation.

According to the characters of the rock mass displacement and deformation for the deep ore deposit excavation,the two-dimensional problem of surface subsidenc due to underground mining is analysed by stochastic medium method and the software ANSYS respectively.
