According to the requirements on the performance of moving deformable barrier (MDB) and test verification method specified in ECER95 regulation,the paper built a finite element model of MDB and carried out the simulation.

Moving Deformable Barrier(MDB) of vehicle side impact is an essential tool for legislative verification of ECER95.

Simulation on dynamic movement and deformation laws of buildings in mining area;

Algorithm of ground movement and deformation prediction in mining of random shape face;

Numerical simulation of the effect of thickness mining and loose seam s thickness on ground movement and deformation in mining subsidence;

Numerical simulation of stress distribution and displacement of rock strata of coal mines by means of DDA method;

This article mainly discusses the process of surveying surface three-dimension on similitude simulation test on mining subsidence indoor,the surveying data can be translated by visual program,surface displacement and deformation can be resulted by its relation,it resolves the difficult problem of how to survey the surface displacement and deformation on similitude simulation test.

Referring to the geological and mining conditions, and according to the mechanism of strata and displacement, the factors affecting the displacement and deformation, and the relationship between forwarding of working face and ground deformati.

The predicting formulas of the tunnel movements and deformations are educed.
