摘要
桥梁深水基础往往处于水深流急,地质条件极其复杂的环境下。而双壁钢围堰具有结构强度高、防水性能好的特点,因此,在桥梁深水基础中得到广泛应用。基于对实际工程的分析,对双壁钢围堰的构造设计、岩面倾斜情况下围堰刃脚的处理措施、围堰稳定性分析、锚碇系统布置及围堰封底混凝土厚度的确定方法等进行了系统的论述。希冀对我国桥梁深水基础的设计和施工有一定的借鉴作用。
Bridge deep water foundation is usually in the environment of deep water, torrent and complicated geographic condition. The double-waU steel cofferdam is widely applied in bridge deep water foundation due to that it is of characteristics of high structural strength and good waterproof performance. On the basis of analysis of practical engineering, the topics such as the structure of cofferdam, treatment of cofferdam edge foot under inclined rock base, Cofferdam stability analysis, laying out of anchorage system and the method to determine the bottom sealing concrete thickness are systematically discussed. It is anticipated that it is of some help to the design and construction of bridge deep water foundation in our country.
