摘要
将边坡临界滑动场方法进行推广与改进,提出挡土结构中的土体主动滑动场的数值模拟方法,并得到相应的主动土压力分布。数值计算结果表明,本文方法精度高,与现有的解析解一致;且可方便地考虑挡墙面的摩擦作用、土体的不均匀分布以及复杂的外载组合,值得推广应用于工程设计。
By extending and modifying the method of critical slip field of soil slope, a numerical procedure is proposed for constructing active slip field of soil behind retaining structures, resulting in the distribution of active earth pressures correspondingly. Results of numerical calculation indicate that the present method is of high accuracy, agrees well with available closed\|form solutions, and is capable of dealing readily with the friction between wall and soil, nonhomogeneity of backfills and complex loading conditions. The method deserves application to practical engineering design.
