摘要
以在建的泰州长江大桥北锚碇(沉井)周边为研究区,用有限元法分析了沉井施工降水过程中地下水运动的变化规律性,从江堤渗透稳定性、整体稳定性及江堤的沉降变形三方面分析了沉井施工降水过程中对江堤安全的影响,工程实践验证了分析计算的合理性。
Taking the north anchorage （caisson） and its surrounding area of Taizhou Yangtse River Bridge in construetion as the study area, the influence on the security of the levee of Yangtse River during drainage for the open caisson＇ s construction is analyzed through three aspects, e.g., infiltration stability, monolithic stability and settlement deformation, and through engineering practices, it is proved that the analysis and calculation are reasonable.
