对重庆轨道交通环线一期工程重庆北站至渝鲁车站施工通道塌方涌水事故进行了分析。通过对水文数据监测、地质水文调查及工程施工的研究,发现施工通道的地下水与旁边的堰塞湖存在水力联系。结合本次塌方涌水的实际情况,提出了3个处理方案。通过综合比较,最终选用钻孔灌注桩水下混凝土封堵填充法施工处理方案,在工程实践中取得了较好的效果。
This paper analyzes the accident of landslide and gushing of the construction passage from Chongqing North Railway Station to Yulu Station in the first phase of Chongqing rail transit loop. Through the monitoring of hydrological data, the investigation of geology and hydrology and the construction of the project, it is found that there is hydraulic connection between the groundwater in the construction channel and the adjacent dammed lake. Combined with the actual situation of this landslide gushing water, three treatment schemes are proposed. Through a comprehensive comparison, the final selection of bored piles underwater concrete plugging filling construction treatment program, the project has achieved good results.
