粉质粘土地基上的节制闸边侧分缝启闭房地基处理方案沉降设计研究

Research on Foundation Treatments’ Settlement of Silty Clay Regulating Sluice’s Separable Hoist Building

摘要: 潮塘江节制闸位于城区，外观要求和安全关注度比较高，闸址土质为粉质粘土，承载力高。为控制闸室两侧启闭房沉降变形，本文通过有限元软件Midas-gts计算分析比选了空箱基础和深层桩基础两种方式的沉降和应力，同时结合建设要求及投资等方面，最终选定深层桩基础作为潮塘江节制闸边墩两侧启闭房的基础处理方式。

Abstract: Chao Tang River Regulating Sluice lying in the town is based on silty clay foundation with higher subgrade bearing capacity, which has higher demands in appearance and safety. To control the settlement of the hoist buildings on both sides of the sluice chamber, box foundation and pile foundation are compared in settlement and stress through Midas-gts in this paper. And combined with the considering of construction requirements and investment, we finally choose the pile foundation.
