摘要: 已运转20余年的连江花溪船闸, 因下闸首地基溶洞压穿, 地基冲刷造成下闸首出现不均匀沉陷.为此, 采用下闸首地基压力灌浆和闸室浇筑混凝土底板的办法, 提高地基承载能力和抗渗能力, 取得良好效果.

Abstract: Huaxi Lock in the Lianjiang River has been in operation for more than twenty years. The set tlements occurred in the lower head of the lock, though in different degrees, are maialy due to the failure of solution caverns under the foundation, and foundation erosion. The pressure grounting technique for the foundation of lower head, and concrete floor placing method for the chamber are used in order to increase foundation bearing capacity and impermeabicity. The methods proved to be effective.

Key words: lower head, foundation, grounting, reinforcement, seepage control
