摘　　要：目的分析辽宁省普通公路岩质边坡在不同防护形式下的稳定性与破坏规律,提出相应的加固治理措施.方法以边坡现场实地调查为主,做好边坡的测量与记录,通过理论分析和工程监测等方法,对辽宁省普通公路岩质边坡稳定性进行系统分析.结果在此次调查的129处岩质边坡中,随着坡高、坡度的增加,岩质边坡的破坏总数也随之增加,其中破坏主要以表面剥落为主.根据调查结果把15 m坡高作为边坡的界限坡高,把55°坡度作为边坡界限坡度.根据不同稳定等级的岩质边坡,采用格构梁式+挡墙支护+坡面植物护坡的加固治理措施方案.结论已有工程实例验证了笔者提出的加固治理措施方案是合理与可行的,且该方案具有较强的针对性与应用价值,可供同类边坡借鉴.The purpose of this paper is to analyse the stability of ordinary highway rock slope under different forms of protection and destruction law in Liaoning province,as to put forw ard the corresponding reinforcement measures. Based on in-situ investigation,making measurement and recording of the slope,theoretical analysis and project monitoring. The systematic analysis of ordinary highw ay rock using slope stability in Liaoning province is carried out. The results show that slope destruction also increases w ith the increase of slope and height,surface spalling are mainly damage in the survey of 129 slopes. According to the survey results, 15 m as the boundaries high,55 degree as the boundaries degree. According to the different grades stability of rock slope,the lattice beam,retaining w all and plant slope protection reinforcement measures are proposed. The engineering examples show that the reinforcement measures proposed by the author are reasonable and feasible. It has very strong pertinence,application value and reference in the similar slope.
