【Abstract】 The method of time-varying mechanics is used to set up a series of basic equations of the incremental model of excavation in the underground engineering. Moreover, the nonlinear computation of three-dimensional excavation problem is carried out. According to the results, the effects of relevance of procedure and dimensions are discussed respectively, and some beneficial conclusions are obtained.更多还原
