| 摘 要： | 以某海峡大桥为例进行深海桥梁基础设计研究,借鉴国内外已建海湾大桥及海上平台的成功经验,选用了沉井基础、吸附式裙式基础、预制桩壳体围堰基础及预制桩沉箱的复合式基础4种形式。沉井基础采用在船坞内整体预制,自浮到深海处接高至整体,通过系泊缆索下沉就位。吸附式裙式基础利用井内抽水形成负压原理将基础下沉到位,不需在井内除土。预制桩壳体围堰基础是先预制管桩,利用打桩船插打管桩形成群桩,吊装壳体围堰后施工承台。预制桩沉箱的复合式基础利用插入土中的钢桩将地基加固,由安放的沉箱传力给地基。

| Abstract: | By way of example of a bridge crossing narrows,the design of bridge foundations located in deep sea is studied.With reference to the successful experiences of the completed bay bridges and offshore platforms at home and abroad,four types of the caisson foundation,absorbing skirt-type foundation,prefabricated piles plus cofferdam shell foundation and prefabricated piles plus caisson combined foundation are selected for the study.The caisson foundation is generally prefabricated in integrity in shipyard,float... |
