摘要
基于ABAQUS并结合工程实例分析了亭子口重力坝坝基水荷载处理方式及效果。结果表明,由于未考虑地基内部渗透压力,在地基表面施加水压力所计算出的竖向应力偏小,剪应力差别不大;单独施加渗流体积力与考虑渗流对应力场的影响两者结果较接近,后者稍大;不同水荷载加载方式下竖向应力和剪应力的分布趋势不变,应力值有所变化。
Treatment and effect of water load of dam foundation for Tingzikou gravity dam are analyzed by using the finite element software ABAQUS combined with the engineering practice. The results show that the calculated vertical stress value under the water pressure loaded on the surface of the foundation is small, and there is little difference in the shear stress for ignoring the internal infiltration pressure of foundation; there is little difference of results under the condi- tion of exerting percolation volume force separately and considering the influence of seepage on stress field, but the latter is larger slightly; under different loading methods of water load, the distribution trend of vertical stress and shear stress does not change while the stress value changes.
