| 中文摘要: |
| 板岩路堑高陡边坡,在开挖施工过程中可能产生的危害性较大.对其不同开挖阶段的扰动效应的分析研究,是一个极有价值的课题,能够为工程的设计、施工提供一定的参考和依据.本文以某高速三合同段的高路堑板岩边坡为依托工程,对天然含水率下的坡体的开挖扰动效应进行极限平衡分析和数值模拟分析.通过研究,揭示了不同工况下边坡的稳定性变化过程,为合理安排开挖工序,选择合理的防护方案,提供了技术参考. |

| The high and steep slate slope is dangerous in the course of excavation and construction.The analysis on the disturbance effect can provide some useful guidance to slope design and construction.Relying on the project of the high and steep cutting slate slope in the third contract section of certain expressway,the influences of every excavating stage with nature moisture content are calculated by limit balance method and numerical simulation method.By analysis,the slope stability of different stages are disclosed,which will provide some useful clues for arranging construction schedules and selecting slope protection method. |
