建筑边坡岩体分类方案的改进

Improvement on Rock Mass Classification Plan of Construction Slop

近十余年来,边坡岩体类别用于建筑边坡工程的多个领域,划分边坡岩体类别成了我国建筑边坡工程中一个基本的要求。研究表明,属于边坡稳定性分类的现建筑边坡岩体分类方案在边坡岩体覆盖范围和边坡稳定性变化规律方面存在一些问题,同时缺少合适的应用领域。另一方面边坡工程又需要属于边坡抗侧向变形能力分类的边坡岩体分类方案。该文根据岩石坚硬程度、岩体完整程度和有无与边坡走向平行的陡倾结构面进行了边坡岩体分类。

As slop rock mass is being adopted in many fields of construction slop project in recent ten years, its classification has become a basic require-ment in Chinese construction slop engineering. The study shows that the construction slop rock mass classification plan which belongs to slop stability classification has some problems in rock coverage and the changing rule of slop stability and lacks in applicable suitable field. While the slop rock mass classification plan which belongs to anti-side transformation capacity type is wanted. Slop rock masses are classified in accordance with rock hardness, rock mass integrity and steep structural plane which is parallel with slop.
