摘　　要：针对苏州独墅湖隧道基础设计要求,经过对多方案分析比选,决定对大断面浅埋隧道结构推荐采用桩基础,这既满足了结构抗浮安全的要求,又起到了控制隧道沉降的作用。此外,对人工筑岛段范围内的桩基础,采用考虑负摩阻力影响的设计方法对类似工程也可提供借鉴和参考。With regard to the design requirements of the tunnel foundation,pile foundation was recommended for Suzhou Dushuhu Lake tunnel which features with large cross section and shallow embedment through comparison of multiple design schemes.The pile foundation could meet the safety of buoyancy,and control the tunnel settlement.For the pile foundation within the man-made island,the negative frictional resistance was considered in design,which will be a reference for the similar projects.
