【摘要】：ATS水电站厂房尺寸较大,主机间长87.6 m,宽43.3 m,水下部分高35 m。由于地形、地质条件的制约,主机间基础位于不同的地基介质上,传统的结构力学方法计算地基应力不能体现地基介质不同对地基应力的影响,需要采用三维有限元方法对其进行模拟计算。根据地质勘察、设计资料,建立三维有限元网格模型,模型模拟了厂房主体结构以及主机间、尾水闸墩下部的地质构造,进行无桩基及有桩基情况下的地基应力和变形对比计算,论证在地质条件不良情况下设置桩基的必要性。
[Abstract]:ATS hydropower plant has a larger size, 87.6 m between mainframes, 43.3 m in width, and 35 M. in the underwater part because of the terrain and geological conditions. The foundation between the main engine is located on the different foundation medium. The traditional structural mechanics method can not reflect the influence of the foundation stress on the ground medium, and the three-dimensional finite element method is needed. According to the geological investigation and the design of the data, the three-dimensional finite element mesh model is set up. The model simulates the main structure of the factory building and the geological structure of the bottom of the tail water gate pier, and carries out the calculation of the stress and deformation of the foundation under the condition of no pile foundation and the pile foundation. It is necessary to demonstrate the necessity of setting the pile foundation under the condition of bad geological condition. It's sex.
