摘　　要：在分析某天然气储配站场地环境地质条件的基础上,对其开挖形成的高边坡采用喷锚及格构锚固措施进行处治;采用重庆市地方规范规定的极限平衡法及数值模拟分析两种方法对边坡处治后的可靠性进行综合评价,结果表明治理工程实施后边坡稳定安全系数达到规范规定,设计锚杆无破坏现象,有效处治的边坡能满足天然气储配站场地环境的安全要求。Based on analyzing the site geological-conditions of a natural gas storage station,a high slope formed by excavating is treated by using spray anchor and framed anchor.Two methods,a limit-equilibrium way from Chongqing local norms and other numerical simulations,are used to analyze and evaluate the treated slope reliability comprehensively.The results show that the slope stability factor,after the implementation of project management,may comply with the requirements of safety norms,and the designed bolts have no damage.The effective treatment of the slope can meet the safety requirements of the natural gas storage station.
