摘　　要：优势结构面对边坡岩体稳定性起控制作用。基于功效系数法的相关原理,在权衡考虑结构面的主要影响因素基础上,确定岩体的优势结构面。研究结果表明,使用功效系数法确定岩体优势结构面,简单易行,且比较符合实际,不失为岩体优势结构面确定的一种新方法,具有较高的工程应用价值。Preferred structure plane plays an important role in the stability of slope rock. Based on the basic principle of efficacy coefficient method,the preferred structure plane of rock was determined by considering comprehensive key factors influencing structure plane. The results show that using the efficacy coefficient method to determine preferred structure plane is simple and conforms to reality,it provides a new method to determine the preferred structure plane of rock and has a high value in engineering practice.
