对于山麓斜坡地带的工程地质勘察,最主要的是了解斜坡的自然稳定状态和由于工程活动而破坏了斜坡的自然稳定状态后是否会引起斜坡体失去稳定而产生滑动或坍塌。滑坡对于工程活动来说是一种较为严重的病害,它不仅给勘察、设计、施工等项工程活动带来很大的困难,如果稍有疏忽,处理不当,则会给建筑场地的使用造成严重的威胁,甚至破坏整个建筑场地。这类例子很多,如成都某物资仓库拟建于龙泉山的山麓斜坡地带,在整平场地时破坏了斜坡体的自然稳定状态而引起斜坡体的大量滑动。斜坡土体大量滑动的结果,给建筑场地的修建造成了很大的困难,不仅增加了建筑投资,缩
For the engineering geological survey of the slopes of mountains and rivers, the most important thing is to understand whether the natural stability of the slope and the natural stability of the slope are damaged due to engineering activities. This will cause the slope to lose its stability and cause sliding or collapse. Landslide is a serious disease for engineering activities. It not only brings great difficulties to survey, design, construction and other engineering activities. If it is neglected and handled improperly, it will cause serious damage to the use of construction sites. The threat even destroyed the entire building site. There are many examples of this type. For example, a material warehouse in Chengdu is planned to be built on the slope of the Longquanshan Mountain. When the site is leveled, the natural stability of the slope body is destroyed and a large amount of sliding of the slope body is caused. As a result of the large amount of sliding of sloped soil, great difficulties are caused to the construction of the construction site, which not only increases the investment in construction, but also reduces the
