13、砂土，厚6.40m9.00m；粉质粘土，厚4.10m640m。由于地下室为两层，埋深为85m，大楼正立面城市道路下埋有煤气管道，15孔电力电缆埋设于人行道下，埋深078m，距离基坑仅为782m， DNl00 E水管道也位于人行道下，直径 900城市污水管埋设于马路中间。由于这些管道埋设环境条件比较高，特别是煤气管道一旦发生变形后破裂，煤气外泄对城市环境破坏将是极其严重的，因此要求深基坑围护设计确保基坑附近市政设施绝对安全，基坑土方开挖后，其变形要小，不影响市政设施安全运行，为此采用冲孔悬臂灌注桩(800mm)和两道迈式锚杆(28钢筋，长15m和12m，孔径为l20mm)相结合的方案。f论文：冲
