| 中文摘要: |
| 本文将边坡临界滑动场方法进行推广和改进，计算挡土结构中土体被动临界滑动场PCSF和被动土压力。首先建立土体极限平衡方程并引入条间力函数，给出平衡方程求解格式；介绍改进的土体临界滑动场数值模拟技术；最后给出实用的被动土压力计算图。本文方法原理简单、精度高，可应用于工程计算。 |
| 英文摘要: |
| By extending and promoting the critical slip field method for slope analysis, passive critical slip fields in retaining structures are numerically computed along with passive earth pressure. The limit equilibrium equations are established with inter-slice force function introduced. The scheme for solving such equations and numerical technique for simulation critical slip field are presented. A monographic chart for determination of passive earth pressure is given. |
