Abstract: The shear parameters are often confirmed by the combination method of practical classification and engineer experi- ence．The national standard Technique Code for Building Slope Engineering(GB 50330-2002)is a practical classification method using willy，and it provides the shear parameters of rock discontinuities of slope．With the increasing in depth of re- searches into experiments of discontinuities and the wide application of the code．this practical classification method needs to be improved．Based on wide surveys，field tests and laboratory tests，the modification suggestion is proposed．The suggestion call make the method more reasonable to supervise the rock slope design．

Key words: Technique Code for Building Slope Engineering, rock slope, discontinuity, shear strongth parameters, classifica- tion method

摘要： 在中小岩质边坡稳定性分析中，常常根据技术规范提供的实用分类方法和工程经验相结合估算结构面抗剪强 度参数．GB50330-2002(建筑边坡工程技术规范》是一种广为应用的实用分类方法，可为边坡岩体结构面提供抗剪 强度参数．随着结构面试验研究的深入和该国标的广泛应用，有必要进一步补充与完善这一实用分类方法．为此，在 广泛的调研、有针对性的现场试验和室内试验的基础上，对该分类方法提出了修正意见，使其更具科学性与实用性， 更好的指导岩质边坡设计．
