南华深基坑稳定性监测分析

South China monitoring analysis of deep foundation pit stability

根据南华深基坑施工的实际情况,确定了螺旋钻孔压浆桩加锚索支护方案,并对基坑各测点沉降的趋势进行了实时监测,监测结果表明,桩顶最大累计水平位移值较大处对应位置均为基坑各侧中间位置,应尽量减少施工扰动,加强降水,必要时需准备沙袋及时回填。

According to actual situation of South China deep foundation pit construction,determined screw drill hole grouting pile plus anchor cable support scheme,the trend of foundation settlement of each measuring point for the implementation of the monitoring,monitoring results show that the maximum accumulative horizontal displacement pile head corresponding position for each side of foundation pit with strong middle position,should try to reduce the disturbance of construction,strengthen the precipitation,prepared sandbags timely backfill as needed.
