【摘要】 采用三维有限元方法对某河床式水电站厂房9#坝段开展整体应力应变和稳定性分析,得到其正常运行工况和检修工况下坝体和坝基的应力应变状态。采用点强度储备安全系数法、建基面整体强度储备安全系数法、以及强度储备安全系数法分析了各工况下9#机组坝段抗滑稳定系数,论证了其稳定安全性,为设计提供了参考。研究表明,沿建基面积分所得强度储备安全系数与降强法所得整体强度储备安全系数误差在2.73%～8.29%之内。更多还原

【Abstract】 Using three-dimensional finite element method to analyze the stress, strain and stability of the 9# dam section of a riverbed hydropower station. The stress-strain state of the dam under normal operation and maintenance conditions are obtained. The point strength reserve safety factor method, the foundation strength reserve safety factor method, and the overall strength reserve safety factor method are used to analyze the anti-sliding stability coefficient of the dam foundation under various working conditions, demonstrating its stability and safety, and providing a reference for the engineering design. The research shows that, the safety factor of the strength reserve along the foundation and the overall strength reserve by the strength reduction method are within 2.73%～8.29%.更多还原
