Underground excavation will influence the safety of the geotechnical surroundings. Based on the stochastic medium theory, influence on the surrounding rock and soil by underground excavation is studied. Formula for predicting movement and deformation of rock and soil mass caused by excavation are deduced, and especially for those with horizontal rectangle section, semi-analytic solution for this problem is put forward. Furthermore, a computer program is developed to compute the movement and deformation of the rock and soil mass resulted from excavation. The theory is applied in an engineering example, which shows that the results of the research are reasonable and the developed solutions can be used for safety evaluation of underground excavations. |
