| 中文摘要: |
| 首先探讨了有限层法求解开挖问题的难点，即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。计算结果同实测值的一致性证实方法了的正确性和有效性。 |
| 英文摘要: |
| The finite layer analysis is applied to solve the 3D excavation problem in transverse isotropic foundation.The finite layer expression of equivalent excavation load and finite layer calculation method of rigidity matrix for excavated pit are studied.On this basis,calculation method for finite layer analysis of excavation problem in layered transverse isotropic soil is established and corresponding computation program is developed.The validity of the method is verified by observation data. |
