汇潭前方闸地基处理方案的分析

On Foundation Treatment of Huitang Gate

水闸地基在不满足竖向承载力、抗渗、抗震等要求的情况下通常需要进行地基处理.以汇潭前方闸地基处理方案为例,按实际情况选择了三种适用的处理方法,并从安全、可靠、经济、施工等方面进行了分析对比,选择了抛石挤压法作为最优方案,工程实施中取得了预期效果.

When the bearing capacity of the sluice foundation fails to meet the requirements of vertical bearing capacity, seepage resistance or seismic resistance, there are varieties of the foundation treatments should be employed. Based on the foundation project of Huitan Gate, three suitable treatments are compared in safety, reliability, cost and construction. At last, the packing up sedimentation by dumping stones is chosen as the optimal scheme and got the expected effect in prac- tice.
