山区建厂中,防止地基、边坡滑坡是设计、施工中应特别引起注意的问题。若防治不好,常招致很严重的质量事故,造成建筑物裂缝、滑移甚至倒坍。现将工程地基滑坡问题和预防整治措施作一简介。一、山区滑坡的类型 1.边坡坡度不够,倾角过大,土体因自重及雨水(或地下水)浸入,剪切应力增加,内聚力减弱,使上部土体失去稳定而滑动。 2.土层下有倾斜岩层,或土层下的岩层虽近于水平,但距边坡过近,边坡倾度过大,在建筑物填土或堆置材料荷重和地表、
In the construction of a mountainous area, the prevention of foundations and slope landslides is a problem that deserves special attention in design and construction. If the control is not good, it often leads to serious quality accidents, causing cracks, slipping or even falling of buildings. Now we will give a brief introduction to the problem of landslides and prevention measures. First, the types of landslides in the mountains 1. The slope is not enough, the inclination is too large, the soil body is immersed due to its own weight and rain (or groundwater), the shear stress increases, the cohesive force weakens, and the upper soil loses stability and slides. 2. There are inclined rock layers under the soil layer, or the rock layers under the soil layer are close to horizontal, but they are close to the slope, the inclination of the slope is too large, and the building is filled with earth or piled with materials and surface,
