白虎潭水库坝高76.30 m,属于高坝,坝基地质条件较复杂。为了检验白虎潭大坝在施工期和运行期是否满足强度要求,需要对坝体进行应力分析。文章采用大型有限元软件ansys分别对溢流坝段和挡水坝段进行计算分析。计算结果表明,在各种工况下,坝体位移在正常范围内,坝体沿坝基的抗滑稳定安全系数及坝基应力满足规范规定和坝基承载力的要求。大坝是安全的。
Baihu Tam reservoir dam height of 76.30 m, belonging to high dam, dam geological conditions are more complex. In order to test whether the Baihutan dam meets the strength requirements during construction and operation, stress analysis of the dam is required. In this paper, large-scale finite element software ansys are used to calculate and analyze the overflow dam and the dam. The calculation results show that the displacement of the dam body is within the normal range under various operating conditions and the stability and safety factor of the dam along the dam foundation and the stress of the dam foundation meet the requirements of the code and the bearing capacity of the dam foundation. The dam is safe.
