| 中文摘要: |
| 边坡失稳是外界各种因素的共同作用下，由局部小范围的变形逐渐延伸扩大最终演变为整体破坏的灾变过程，在此过程中，控制边坡变形的因素也是“动态”变化的.对未支护下的边坡进行多级开挖，分析不同开挖时步下的坡体稳定性及其变形，根据其计算结果对边坡进行分级支护，分析支护后的坡体稳定性及其变形.对比结果表明，采用及时支护方式开挖的边坡安全系数在开挖早期有所降低，但后期逐渐增加，支护后坡体各监测点的水平位移和竖直位移均小于未支护前. |

| The stability of slope is a combination of external factors.By the local deformation extended and evolved into the overall destruction of disaster process eventually.In the process，the factors of controlling the deformation of slope is “dynamic”.The multistage slope of not supported is excavated.The stability and deformation of slope are analyzed under different steps.The slope is supported according to the results of the calculation.The stability and deformation of slope are analyzed under supported.The comparison results show.If the slope is supported in timely.The safety factor of slope is reduced in the early excavation.But it will increase in the late.The monitoring points of horizontal displacement and vertical displacement of the slope both reduce after supported. |
