基于ANSYS的严寒地区拱坝稳定及应力分析

摘要

大坝口水库工程为浆砌石双曲拱坝,具有以下特点:地处严寒地区、年内温差大、河段来水含沙量大、泥沙淤积严重、Ⅶ度地震等.设计中针对这些特点以及地质、地形情况,并结合本工程任务,合理地进行了挡水建筑物布置、泄水与排沙建筑物布置、取水建筑物布置等,改善了坝肩的稳定条件.本文通过ANSYS进行坝肩抗滑稳定分析和坝体应力分析,结果表明坝肩抗滑稳定和坝体应力均满足要求.本工程设计具有一定的代表性,值得类似工程参考.%Dabakou reservoir project of masonry double-curvature arch dam has the following characteristics:located in the arctic region,large temperature difference,water in river sediment large,serious silting,Ⅶ degree earthquake.Design based on these characteristics and geological,topographical condition,and combined with the engineering task,reasonably water retaining building layout,discharge and sediment structure layout,water intake structure layout,improve the stability of the dam abutment conditions.This article analysis the dam shoulders anti-sliding stability analysis and dam stress analysis based on the ANSY.The results show that the stability against sliding of dam abutment and the stress of dam body meets the requirements.This engineering design has a certain representation,worthy of reference for the similar projects.
