摘　　要：在富水砂层条件下施工锚索时,常常发生锚索涌水涌砂现象及成桩质量差等问题。论文以某实际深基坑支护工程为案例,阐述了解决深厚富水砂层中成桩质量问题及应对锚索施工中的涌水涌砂问题的处理对策,并通过锚索内力监测数据和桩体检测结果证明了该工程处理措施切实可行,为此类深厚砂层中的深基坑支护工程设计提供参考。In the construction of anchor cable under the condition of water-rich sand layer,water and sand gushing of anchor cable and poor quality of pile forming are often occurred.Taking an actual deep foundation pit supporting project as an example,this paper expounds the countermeasures for solving the quality problem of pile forming in deep water-rich sand layer and the measures for solving the problem of water and sand gushing in anchor cable construction,the monitoring data of the internal force of the anchor cable and the test results of the pile body prove that the engineering treatment measures are feasible and can be used for reference in the design of the deep foundation pit support engineering in this kind of deep sand stratum.
