一、编制依据
1.1、昆明绕城高速东南段B1工区施工设计图； 1.2、交通部颁发标准和规范、规程：
(1) 《公路工程质量检验评定标准》（JTG F80/1-2004） (2) 《公路工程安全技术规程》（JTJ076-95） (3) 《公路路基施工技术规范》（JTG F10-2006）
二、工程概况
2.1、锚杆框格梁施工里程部位
2015年3月27日业主及设计方对已完成刷坡的边坡进行现场勘察研究后，确定K70+850～K71+025段路基左侧第三级边坡、K70+205～K70+370段路基右侧第二级边坡采用锚杆框格梁护坡。
2.2、工程地质及水文地质情况
(1) 地形地貌
线路所经区域为滇中高原的一部分，地形较为复杂，其自然环境地表崎岖，群山连绵，山脉呈南北向延伸，与构造线基本一致。
本项目K66+440～K71+470.08段属低中山构造剥蚀、溶蚀地貌单元。 (2) 工程地质条件
路线所经区域出露的地层主要有元古界昆阳群、震旦系、寒武系、志留系、泥盆系、石炭系、二迭系、第三系、第四系地层。
路线所经区域构造体系形迹主要有南北向构造体系、东西向构造体系、新华夏构造体系以及“入”字型构造体系。
在K71+360附近与路线呈约20度交角通过F4断层（南北走向）。 (3) 气候及水文
路线区域属亚热带高原季风气候，具有冬暖夏凉四季如春的特点。
年平均气温14.6℃；多年平均降雨量1040mm，雨季多集中在5～9月，约占全年降水量的70～80%；年蒸发量1500～2100mm；最强3～4月；多年平均绝对湿度13，相对湿度74%。
本项目地下水类型可划分为：松散岩类孔隙水、基岩裂隙水、岩溶水三类，赋存
