2、治理效果进行评价;采用GEO-SLOPE进行数值模拟分析,判断边坡的稳定性是否满足要求,然后提出用抗滑桩治理滑坡的方案,最后按照有关规范进行设计工作;根据相关工程背景,结合有关勘测资料,采用GEO-SLOPE对膨胀土边坡的稳定性进行数值模拟分析,得其边坡安全系数K=1.047<1.3,不满足稳定要求;采用抗滑桩结合设置排水措施进行治理,使其满足稳定要求;结合工程实际,按照规范对其抗滑桩进行设计,结果进行人工挖孔灌注桩加固处理后,边坡稳定性大大提高,安全系数为1.304,满足工程设计要求;运用GEO-SLOPE商业软件对治理前后的边坡进行稳定性分
3、析,从相关分析数据中可以看出,抗滑桩的设置大大限制了滑动面的范围,对减小可能的滑坡规模和提高边坡的整体稳定性效果十分明显。关键词:膨胀土;边坡;GEO-SLOPE;稳定性分析;数值模拟;膨胀土边坡治理49AExpansiveSoilSlopeReinforcementDesignHuJiabiaoYunnanAgricultureUniversity,WaterconservancyandhydropowerandarchitecturalKunming650201ABSTRACTMasterofexpansivesoilslopeengine
