交互效应对滑坡稳定性的影响
|
Abstract:
滑坡稳定性受多种因素的影响,如地震加速度、内摩擦角、粘聚力、库水位变化、岩体密度等。这些因素并不是相互独立的,往往存在着相关性,这些相关性对滑坡稳定性会产生显著影响。本文对滑坡试验中的相关数据进行分析,同时考虑因素的主效应和交互效应,从而得出地震加速度与粘聚力、内摩擦角的交互效应对试验结果有显著影响,并根据所得模型求出最优解。在此基础上得到的各因素的最佳水平组合比以往的文献稳定性更优。因此在滑坡处理的过程中,我们应特别注意地震与降雨的交互效应对滑坡稳定性的不良影响。
The stability of landslide is affected by many factors, such as earthquake acceleration, internal friction angle, cohesion, reservoir water level change, rock mass density and so on. These factors are not independent, there are often correlations, and the correlations will have a significant impact on the stability of landslides. In this paper, considering the main effect and interaction effect of factors, we obtain the interaction effect of seismic acceleration, cohesion and internal friction angle has a significant influence on the test results. The optimal solution is obtained according to the model. The optimal level combination of the factors obtained on this basis is more stable than the previous literature. Therefore, in the process of landslide treatment, we should pay special attention to the interaction between earthquake and rainfall on the landslide stability.
