摘　　要：开利公路K38+150～K38+350段边坡失稳变形是典型的顺层岩质边坡在施工过程中的失稳变形现象。通过现场地质调查和计算分析,查明了边坡失稳的机理和控制因素。在此基础上,经过综合分析,采取了"清方+锚杆(索)框架梁+排水"的综合治理措施。该加固工程竣工已两年有余,至今该段边坡没有发现失稳变形迹象,表明所采用的边坡处治措施是科学合理的。The slope failure at K38＋150～K38＋350 in Kaili highway was a typical example in the construction of bedding rock slope.Based on the detailed geologic survey and the calculating and analyzing,the mechanism and key factors resulting in the failure of the bedding rock slope were investigated,and an integrated reinforcing technique,which were ＂de-loading ＋ anchoring ＋ draining＂, was used in the project.In the past two years since the reinforcing project finished,the slope was continuously stable,which indicated that the reinforcing technique was reasonable for slope treatment.
