| 中文摘要: |
| 混凝土重力坝的承载能力是高坝设计中重要的研究课题。本文根据应变空间表述的弹塑性增量理论，采用稳定性分析方法研究重力坝的承载能力，给出混凝土重力坝与坝基岩石系统失稳的判别准则，同时按两种不同的材料强度储备方式，研究重力坝的承载能力。这种方法能反映因混凝土和岩石材料损伤和软化导致重力坝系统失稳的物理机制，使分析建立在一个严谨的力学基础之上。计算实例表明，本方法可作为一个合理和可行的分析方法。 |
| 英文摘要: |
| Based on the elastic-plastic increment theory the bearing capacity of concrete gravity dam is studied using stability and analytic method expressed in strain space. Criterion for stability of concrete gravity dam and foundation rock system is proposed. Two kinds of material strength margin are considered in the study. This analytical method is able to reflect the physical mechanism of concrete gravity dam system if unstable state is occurred due to damage or softening of concrete and rock. The calculation result indicates that the method is rational and feasible. |
