摘要
本文首先探讨了有限层法求解开挖问题的难点:开挖等效荷载的有限层表达和开挖后刚度矩阵的有限层计算,并在此基础上建立了三维横观各向同性土体开挖问题的有限层求解格式,并编制了相应的计算程序。计算结果同实测值一致性证实了方法的正确性和有效性。
The finite-layer method is widely used in the goemechanics. It is now extended for 3-D excavation problem of the transverse isotropic soil. Its solution procedure is derived for the excavation problem in the paper. There some difficult points are discussed. Especially, the expression of the equivalent excavation load and the stiffness matrix after excavation are focused. At same time, a computer program is developed. The computing results are compared with that of the measured one. The results are shown that there are agrees.
