Due to the limitations of geography and geology, cast concrete tunnel anchors were used provide counterforces for Xingkang Suspension Bridge foundation at left bank Daduhe River. In this study, in situ creep tests conducted on two model a scale 1:10 near real working anchor site. Thus, long‐term deformation installed bridge could be determined from test anchors. The under three different loads lasted 102.2 h, 167.5 189.4 respectively. anchor, surrounding rock, their interface all monitored...
Due to the particularity and complexity of loess, it is challenging estimate its collapsible behavior numerically at present. This paper aims propose a simplified approach, which named as modulus reduction method, loess. For loess upon wetting, method assumes that collapses result strength due additional stress induced by increasing bulk density. Thus, special attention given confirmation determination approaches density deformation wetting. Subsequently, comparative numerical analysis based...
Daguangbao landslide is the largest triggered by Wenchuan earthquake. How did it reach high speed and long-runout?This question attracted wide attentions of scholars at home abroad. This paper aims explanation for mechanism high-speed long-runout adopts velocity-depending frictional weakening sliding bed due to thermal decomposition dynamic crystallization. modifies input manner strength parameter in Discontinuous deformation analysis(DDA)method. The constant original DDA replaced parameter....
