山区建厂由于受到场地地形限制,有些工程常紧靠陡坡岩岸设置,坡顶积有大量多年冲蚀的悬岩、孤石和直径很大的探头大块石(图1),有的高出厂房10～20米,如不妥善处理,对附近建筑物的安全带来很大威胁。又如在平整场地时,新开岩石(如泥岩,页岩)和土的边坡,长期在空气中受雨水冲蚀,亦会很快风化剥落,影响边坡稳定, In the mountainous region, due to the topography of the site, some projects are often located close to the steep slopes. The top of the slope contains a large number of overhanging hanging rocks, lone stones, and large-diameter probe stones (Figure 1). Some of them are high. Plants 10 to 20 meters, if not properly handled, pose a great threat to the safety of nearby buildings. For example, when the site is leveled, newly-opened rocks (such as mudstone and shale) and soil slopes will be washed away by rain in the air for a long time, and will be weathered and flaking quickly, affecting slope stability.
