针对新疆地区某水电站高耸进水塔地基不能满足上部结构要求的问题,采用PKPM软件中桩筏有限元计算模块和ADINA有限元软件,对高耸进水塔三种地基处理方案进行了计算分析。结果表明,桩基础、深齿墙+桩基础、无桩深齿墙三种方案均满足上部结构承载的要求;通过对比三种方案五个工况下的最大沉降量、应力及安全性等,并结合该高耸进水塔的项目特点,最终推荐选择无桩深齿墙方案。
Aiming at the problem that the tower foundation of a towering water tower in a hydropower station in Xinjiang can not meet the requirements of the superstructure, the PKPM software-in-the-pile finite element calculation module and the ADINA finite element software are used to calculate and analyze the three foundation treatment schemes of the towering water tower. The results show that the three schemes of pile foundation, deep toothed wall + pile foundation and non-pile deep toothed wall all satisfy the requirements of superstructure loading. By comparing the maximum settlement, stress and safety under the three conditions of three schemes, Combined with the project characteristics of the towering water tower, the final recommendation is to choose a non-pile deep-tooth wall program.
