邻江特大异型基坑施工的风险分析

On risk analysis of super-large unique foundation pit near rivers

以某邻江特大异型基坑为背景,对基坑施工的过程进行了风险识别、风险分析、风险评估,建立了基坑施工的风险评价体系,提出基坑开挖、基坑降水、底板施工等阶段的风险控制措施,取得了比较好的效果,为今后类似工程提供有益的借鉴。

Taking some super-large unique foundation pit near rivers as the example, the paper undertakes the risk identification, the risk analy- sis, and the risk evaluation of the foundation pit construction process, establishes the risk evaluation system of the foundation pit construction, points out some risk control measures at the foundation excavation, the foundation watering, and the bottom plate construction, and achieves bet- ter effect, so as to provide beneficial reference for similar projects in future.
