摘要
本文利用非线性有限元计算和地质力学模型试验,就水利工程中常见的,双斜复合滑裂面岩基上混凝土重力坝的抗滑稳定问题进行了研究。着重探讨坝基系统的应力分布、变形状态、破坏形式的变化规律,以阐明其破坏机理和对系统稳定安全度的影响.
In this paper,both the non-linear finite element method and geomechani- cs model test are used to study the stability against sliding of concrete gravi- ty dam on rock foundation with dual-inclined complex sliding plane which are often met in hydraulic engineering.Emphasis is laid on the investigation of the laws of variation of the distribution of stress and deformation,and iu the shapes of failure of dam-foundation systems.
