苏通长江大桥引桥试桩工程的检测和施工建议

Proposals for Detection and Construction of Test Pile Works for Approaches to Sutong Bridge across the Yangtze River

为了正确指导苏通长江大桥引桥和主桥钻孔灌注桩的施工,按照江苏省苏通大桥指挥部的部署,先后进行两期工程试桩,其中一期试桩是针对引桥桩基。根据苏通大桥一期试桩检测结果,分析一期试桩所暴露出来的问题和原因,并针对试桩中所存在的问题,提出对引桥桩基正式施工的一些建议。

For correct guidance to bored in-situ pile construction for the approach and main bridge of Sutong Bridge across the Yangtze River, pile test is performed in two stages as arranged by the Headquarters of the bridge. The first stage test is for the pile foundation of the approach. Analysis is made of the problems and their causes found in the first stage test, with proposals against them for the formal construction of the approach pile foundation.
