| 摘 要： | 通过离心模型试验,分别从坡顶位移、坡面水平位移及坡内位移的角度,分析在相同加固条件下坡体位移变形的特征,研究了坡体失效变形模式.试验研究表明:注浆钢管微型桩能有效地控制边坡土体的位移和坡体内裂缝;加固后的边坡滑动面深度将发生下移,从而阻止滑坡的形成;相同加固条件下的边坡含水量对加固效果起控制作用,即当含水量超过一定值后...

| Abstract: | Displacement characteristic and failure mode of slop was analyzed from the aspects of displacement of slope top,horizontal displacement of slope surface and displacement of internal slope through centrifugal model test when the slop was reinforced in the same way.The experimental result shows that(1) grouted steel tube micropiles can effectively control the displacement and crack of slope soil;(2) the slide surface of slope will move down after reinforcement to prevent the generation of landslide;(3)the wat... |
