中里滑坡位于延吉至图们高速公路右侧 ,由于高速公路路基开挖切断原山脊形成滑坡。在滑坡稳定性评价及滑坡推力计算中 ,滑带土抗剪强度的确定直接影响稳定性评价结果与治理方案设计 ,对该滑体的治理工程造价起着重要的影响。针对中里滑坡目前正处于滑动阶段的特点 ,及滑带土抗剪强度指标的确定在分析计算中的重要性 ,运用反分析方法 ,给出比较合乎实际的滑带土综合抗剪强度指标c、φ值 ,为进一步计算、评价、治理提供可靠的依据。
The landslide of Zhongli is located on the right side of Yanji-Tumen Expressway. As a result of excavation of expressway subgrade, the original ridges form a landslide. In the landslide stability evaluation and landslide thrust calculation, the determination of the shear strength of soil in the slip zone has a direct impact on the stability evaluation results and the design of the treatment plan, which plays an important role in the cost control of the landslide. In view of the fact that the Zhongli landslide is currently in the stage of sliding and the importance of determining the shear strength index of the landslide zone in the analysis and calculation, the comprehensive shear strength index of the landslide soil c is given by using the back analysis method. φ value, in order to further calculate, evaluate, provide a reliable basis for governance.
