重力式码头倾斜基岩面的施工处理

为使预制构件底面与基床接触良好和利于构件安装,抛石基床均须进行夯实和整平,对于岩石地基也可根据结构形式直接在岩面上浇筑砼或表面处理后安装、砌筑预制块体。特别对于较陡基岩坡面,若不经施工处理而直接在岩面上设置基床,则在接触面有可能产生滑动,从而造成码头结构破坏。

Treatment of Inclined Rock Base for Construction of Gravity Quay

Riprap foundation bed shall be tamped and leveled to make the bottom of precast structure have a good contact with it and to facilitate the installation of present structure. On rock base, concrete structure may be cast in-situ directly, or if treated properly on the surface, precast concrete blocks may be installed and placed. Especially for the steep rock base, slippage may take place on the interface of foundation bed without any treatment of the surface of rock base in construction, which may give rise to structure failure of quay.
