Since geological conditions in these regions are very complex and folds and fault structures are widely distributed, to deal with heavily weathered rock slopes is the key technology for constructing high grade roads.

而我国西部地区地质条件极为复杂，褶皱和断层构造广泛分布，对强风化岩质边坡的有效治理是西部地区高等级公路建设中的关键环节。

The conclusions are as follows: ( 1) Because of bad physical mechanical property of rock mass, low strength, so many structural planes and minor faults which leads to weak strip after weathered, the homeostasis of the slightly weathered rock slope is serious.

得出以下主要结论：（1）浅变质岩风化层边坡岩体的物理力学性质差，强度低，坡体内构造面、小断层发育，风化后形成软弱带，导致浅变质岩风化层边坡自身稳定性差。
