摘要
基于水工结构可靠性设计标准,对目前水工结构可靠度的＂作用效应~结构抗力＂分析计算模型进行分析。通过对坝基面抗滑稳定及混凝土重力坝材料强度极限状态分析发现,采用以概率理论为基础的极限状态设计方法更为简便。将可靠度理论应用于水工结构稳定性计算,依据水工设计规范对可靠度方法中系数取值进行分析,将复杂计算方法简单化,对水工结构中概率极限状态设计法提出建议。
Based on unified design standard for reliability of hydraulic engineering structure,it analyzes action effect and structural resistance of hydraulic structure ’ reliability calculation model.Through anti- sliding stability analysis and limit state of the material strength analysis for the concrete gravity dam,it finds that probability limit state design method is more convenient and makes an analysis on the stability of hydraulic structure by the method of reliability. It analyzes the factors of design specification for hydraulic structure,and eases the complex calculations. Put forward some suggestions according to probabilistic limit state design method of hydraulic structure.
