摘　　要：钱江新桥桥位距离旧桥桥址较近,因此其钻孔桩施工有可能对既有二桥桥墩和上部结构产生影响。假定土体为各向同性弹性体,利用Sagaseta(1987)提出的源汇法来对钻孔桩施工产生的土体位移进行研究,对计算成果进行分析,并与实测结果进行了比较。Bored pile construction of the new qiantang river bridge may have influence on the second qiantang river bridge pier because of the short-distance between them.With the application of image method proposed by Sagaseta (1987),the displacements caused by the construction of bored pile are deduced by supposing that the soil is isotropic elastic body.The calculation results are analyzed,and compared with the measured results.
