洪泥河倒虹吸地基主要持力层为淤泥、淤泥质粘土、厚层粉土, 由于地下水位较高, 使用常规方法在基坑开挖、降水的过程中出现了围堰坍塌、裂缝, 基坑涌水、涌砂等问题. 通过科学分析、计算, 采用钢板桩支护方案解决了围堰边坡滑塌问题, 采用井点降水成功降低了基坑水位, 确保了后期工序正常开展.

Main bearing layer of foundation of Hongnihe inverted siphon is silt ,silt clay,and thick layer of silt .Due to the high groundwater level ,conventional methods in the process of foundation pit excavation and dewatering caused cofferdam collapse,cracks,discharge into foundation pit ,sand gushing and other issues .Through scientific analysis and calculation , using steel sheet pile supporting programs settled the problem of coffer dam slope collapse ,and using well point dewate-ring lowered water level of foundation pit successfully ,this project ensured the later stage performed normally .
