燕官公路K102滑坡变形特征及原因分析

K102滑坡位于青海省燕官公路,为一大型堆积层老滑坡,具多级、多条的滑动特征,属牵引式滑坡。文中主要对老滑坡中局部复活的滑体即#1,#2滑坡的变形特征及其机理进行分析,阐明两个滑坡均具浅、中和深三层滑带,有多级滑坡后缘,滑体物质含水量较高,为高含水地段滑坡。最后提出了整治措施建议。

Deformation Characteristic and Cause Analysis of K102 Landslide in Bayan-Guanting Highway

K102 landslide,located in Bayan-Guanting Highway,is a large-scale landslide in accumulated layer occurred frequently,with multiple levels and multiple lines,belonging to traction landslide.This paper mainly analyzes deformation characteristics and mechanism of recovered sliding mass,i.e.No.1 and No.2 landslide in central part of the old landslide,and describes that these two landslides have shadow,medium and deep sliding strips,with multilevel landslide margins and high water content in sliding mass,belonging to landslide in high-water-content section.Finally,it puts forward suggestions for treatment measures.
