降雨强度和降雨持续时间是主要影响因素
降雨强度对边坡稳定性的影响最大最敏感。通过分析
发现进行边坡优化设计和滑坡灾害防治处理时
应对边坡场地周边的降雨强度和降雨持续时间的统计资料予以足够的重视。
Abstract
This article focuses on the impact of rainfall infiltration on landslide.Using five parameters
such as rainfall intensity
rainfall duration
slope ratio
slope height
and the rock mass permeability coefficient
the research builds grey correlation model by using grey correlation analysis from grey theory to study the impact of rainfall infiltration on landslide stability.The analysis shows that the intensity and the duration of rainfall are the main influencing factors
with rainfall intensity being the primary trigger of landslide.The research sheds light on future slope optimization design and landslide prevention
highlighting the importance of analyzing statistical information of rainfall intensity and rainfall duration in the area where slopes are built.
