摘要
通过对某顺层古滑坡的现场调查,分析判断了古滑坡的滑动范围、滑动面,并对滑动面抗剪强度参数进行了反分析计算。据此对古滑坡体进行了初步整治设计,实际整治时未采取防水措施,抗滑指标进一步下降,笔者对此时软化后滑动面抗剪强度进行了计算分析。结合对K89～K95段的调查分析,对此区段的切方边坡违背工程地质选线原则导致的后果进行了反思。
The paper analyzes the sliding range and sliding surface of an old landslide by investigating an old sliding slope. In addition, back analysis is used on shear resistance parameters of slide surface. Primary treatment design of the old slope is carrying out. Measure for preventing water is not carried out at present. The quota of anti-slide come down further. Calculation analysis of stress of soften sliding surface is carried out. According to the investigation on K89-K95, the consequence resulted from disobeying the principle of selected route of engineering geology is thought again.
