摘要： 滨海水闸基础位于深厚软土区，由于水闸各部分地基处理方式不同，建筑物在荷载作用下，易产生差异沉降，加上闸室两侧填土过快，产生不均匀沉降，致使水闸垂向止水破坏；在潮汐的作用下两侧填土被海水掏空，形成渗流通道，成为水闸安全的隐患。针对水闸的结构特点，分析其存在的问题，采用两端膨胀橡胶止水和中间化学灌浆处理恢复垂向止水，采用微劈裂充填灌浆处理水闸两侧绕渗，从而解决软土地基水闸的渗漏问题。

Abstract: For sluices in soft soils,it iscommon that different portions of the sluice foundations are improved with different soil improvement methods. Under the structural loadings, differential settlement might be occurred. Further, due to the fast soil back filling at both sides of a sluice structure, the induced differential settlement would result in the unintended vertical seepage around the sluice structure. Soils at the both sides of the structure might also be scoured away by the tidal wave action. The seepage around the structure is a potential safety hazard to the operation and need to be mitigated. An innovative sluice structure seepage mitigation method using expansive rubber at sides plus the chemical grouting in the middle to prevent the seepage in the vertical direction. The pressure split grout was also used to stop the leakage around the sluice structure.
