对某混凝土面板堆石坝的抗滑稳定浅层次研究

Shallow research on anti-sliding stability of a concrete face rockfill dam

边坡稳定性和滑裂面分析在土石坎稳定性研究中很重要。滑裂面情况的研究是边坡稳定性的前提,滑坡事故的很多原因就是由于对滑裂面形式预估有偏差,导致模型选取不当和实际情况偏差过大,计算结果不可取。所以在分析土坝边坡稳定性时,一定要认真研究可能会产生的滑裂面形式并为之选取正确的计算模型。

With the increasing application of earth-rock dams nowadays,the research on stability of earth-rock dams is very important,especially slope stability and slip surface analysis are more typical.The stability of slope engineering is one of the main research directions of geotechnical engineering.In the long-term practice of slope engineering,the safety factor method is widely used in the judgment of slope stability.The study of slip surface conditions is a prerequisite for slope stability.Many reasons for landslide accidents are due to deviations in the prediction of slip surface forms,resulting in improper model selection and excessive deviations from actual conditions.The calculation results are not desirable.Therefore,when analyzing the stability of earth dam slopes,we must carefully study the form of slip surface that may occur and choose the correct calculation model for it.
