摘要
重力坝抗滑稳定分析的目的是核算坝体沿坝基面抗滑稳定的安全度.以陀兴水库浆砌石溢流重力坝的抗滑稳定分析为例,应用ANSYS有限单元法对该重力坝建模、施加荷载及利用后处理功能计算坝基面的抗滑稳定安全系数,并通过传统的刚体极限平衡法对结果进行验算.结果表明,同工况条件下,两种方法计算的安全系数差别不大,结论可靠,该溢流重力坝满足抗滑稳定要求.
The purpose of anti-sliding stability analysis for the gravity dam design is to analyze the safety degree of anti-sliding stability of the dam foundation surface. Taking a masonry overflow dam for an example, how to build a dam model, define loads, and use the general post processor to calculate safety coefficient of anti-sliding stability of the dam foundation surface by ANSYS software are intro- duced in detail in this paper. The calculation results are checked by traditional rigid limit equilibrium method. The results show that in the same working conditions, the difference of safety factors calculated by the two methods is not big, thus the conclusion is reliable, and the designed overflow gravity dam can meet the anti-sliding stability requirements.
