Investigation on Characteristics of Large-Scale Creep Landslides

Conference paper

Abstract

Two large-scale creep landslides occurred at Taipingshan in Chenxi township of Shangyu District in July 11, 2015 and at Chengjiashan in Xinchang County in November 28, 2016, respectively. The field monitoring of cracks, surface displacements and deep horizontal displacements of the landslides were carried out. Such examinations were combined with site geological investigation, site engineering geological survey and permeability test. The characteristics, formation mechanism and failure mode of the landslides were investigated. The results show that: (1) the total volume of Taipingshan landslide is around 1.05 × 106 m3 with 150 to 180 m wide and 75 to 105 m wide at front and trailing edges, respectively, and the landslide is mainly composed of Quaternary slope bed and fully weathered granite; (2) the total volume of Chengjiashan landslide is around 4.0 × 106 m3 with 480 m wide and 100 m wide at front and trailing edges, respectively, and the landslide is a typical large-scale soil landslide in basalt platform; (3) heavy rainfall and human engineering activities are two major factors causing new deformations of large-scale creep landslides; (4) Large-scale creep landslide is usually tractive and it is in a state of creeping deformation with slow speed of sliding until obvious deformation will occur if there are heavy rainfall or human engineering activities to take place.
