苏宝河流域地震滑坡运动特征研究
Study on motion characteristics of seismic landslides in Subao River Basin
摘要
Abstract
Based on the statistic data of seismic landslides in Subao River basin and with the maximum horizontal displacement ( Lmax ) and the apparent friction coefficient ( Hmax/Lmax ) as the evaluation indexes, mathematical statistic methods were used to discuss the impact on various seismic landslide movement by four influential factors including landslide height ( H ) , landslide slope ( α) , motion area slope ( β) and site type ( X ) . In terms of the impact on Lmax , when the landslide area is over 1000 m2 , the order of influence from high to low is:H,α,β, X;when the landslide area is smaller than 1000 m2 , the order of influ-ence is:H, X,α,β. The significance analysis shows that H is the decisive factor influencing Lmax and not constrained by the area of landslide. In terms of the impact on Hmax/Lmax , when the landslide area is over 1000 m2 , the order of influence from high to low is:α, H,β, X;when the landslide area is smaller than 1000 m2 , the order of influence is:H,α,β, X . The significance a-nalysis shows that H,α,βhave significant impact on Hmax/Lmax when the landslide area is smaller than 1000 m2;the four influen-tial factors do not have significant impact on Hmax/Lmax when the landslide area is over 1000 m2 .关键词
