| 摘 要： | 通过现场工程地质勘探、室内物理力学实验并利用FLAC2D数值分析软件对陕西旬阳县某堆积层边坡进行变形特征的实例分析,考查了坡体岩土体的粘聚力、内摩擦角数值与坡脚开挖深度的变化后,得出浅层岩土体较深层岩土体的滑动趋势与滑动位移均较大,并且浅层岩土体滑移变形对深层岩土体具有牵引力作用。最后对该类型堆积层坡体滑动的防治措施提出了一些看法。

| Abstract: | Using the FLAC2D numerical analysis software, through collection, arrangement and analysis of related data, a site investigation and exploration of engineering geology, and indoor and outdoor physico-mechanical tests were conducted. The deformation properties of No. 6 slope by the 210 State Road in Xunyang county, Shanxi was studied. The changes of the soil and rock internal friction angle, soil and rock cohesion and slope toe excavation were examed, which indicated that there was traction force between the shallow soil and rock layer and the deep soil and rock. The shallow soil and rock layer has generally larger displacement than the deep one. Finally the paper proposed some ideas of prevention for the this type of accumulative slope. |
