摘　　要：某工程基坑主要处于淤泥土中,采用土钉锚杆支护形式,无法满足保护周边建筑物的安全要求,采用钻孔桩+锚索或内支撑方法,造价高,工期长,设计采用加筋水泥土桩锚基坑支护,并对深基坑变形与位移进行全过程监测。结果表明:基坑最大水平位移13 mm,小于规范规定的30mm要求。基坑最大沉降位移15mm,小于规范规定的25mm要求。The foundation pit of a building is mainly located in muddy soil and soil nail anchor support can not satisfy the safety requirements of surrounding buildings.Considering that bored pile plus anchor cable or internal support requires high construction cost and construction period,so reinforced cement-soil pile anchor is design for foundation pit support and deformation and displacement of deep foundation pit are monitored.It is found that the maximum horizontal displacement of foundation pit is 13 mm which is less than 30 mm specified in code,and that maximum settlement displacement of foundation pit is 15 mm which is less than 25 mm specified in code.
