一、前言河北省某港新建三千吨码头,位于渤海湾西南岸一河口内。由于此处地基是软土,不能采用重力式结构,所以在初步设计中曾做了高桩、板桩和灌注桩三种不同结构型式的方案。高桩与板桩的结构型式在码头上早已被广泛采用,灌注桩目前还不多见。然而,由于灌注桩施工简单,造价低,而且承载能力高,在码头结构中推广应用还是很有前途的。为了对灌注桩的码头做进一步的研究,我们以此港三千吨 I. Preface A new 3,000-ton wharf in a port in Hebei Province is located in the estuary of the southwest coast of Bohai Bay. As the foundation here is soft soil, can not be used gravity structure, so in the preliminary design has done high pile, sheet pile and bored pile three different types of programs. The structure type of high pile and sheet pile has been widely adopted on the wharf, and the bored pile is still rare at present. However, due to its simple construction, low cost and high bearing capacity, the bored pile is very promising in popularization and application of the wharf structure. In order to do further research on the pier of the piles, we use it as a port of 3,000 tons
