摘要:
类土质滑坡具有独特的性质，对其进行研究具有重要意义。本文首先选取滑坡稳定性的主要影响因子，并基于正交统计学方法及GeoStudio数值模拟软件，研究各影响因素对滑坡稳定性影响的显著性；再利用直剪试验分析各显著影响因子之间的相互关系，掌握其相互作用规律。结果表明：在滑坡稳定性影响因素的敏感性研究中，滑带土内摩擦角、降雨强度及滑带土内摩擦角与降雨历时的交互作用对类土质滑坡稳定性的影响均较为显著；另外，在影响因子相互作用的规律研究中，降雨对滑坡土体抗剪性质的影响主要是通过改变滑坡土体含水量来实现的，而土体含水量对不同类土质土体抗剪强度的影响具有相似性，但影响程度不一致，其原因主要是由于其矿物成分组成及含量的差异造成的。上述对类土质滑坡稳定性影响因素的研究，为类土质滑坡成因机理的分析提供借鉴和参考。
Abstract:
Class soil landslides have unique properties, the research on it has the important significance. Firstly, the main factor on landslide stability was selected, and based on statistical methods and GeoStudio orthogonal numerical simulation software the various factors affecting the stability of the landslide were significant; and the direct shear test was use to analyze each factor significantly affecting the interaction between the master of its interaction law. The results show that the sensitivity of the factors affecting the stability of the landslide such as sliding with friction angle of the soil, rainfall intensity and sliding friction angle of the soil with the effects of the interaction of rainfall duration and soil slope stability class had the most significant effects; in addition, the law of the interaction factor, the effect of rainfall on the shear properties of the main landslide by changing the water content to achieve, while the soil water content of different types of soil shear strength of the soil had the similar impact, but the impact was inconsistent, the main reason was due to its mineral composition causing the inconsistencies. The study results of factors affecting the stability of the landslide soil class above provided the foundation for the future research on soil landslide.
