摘要: 通过地表系统测绘并配合大量的钻探工作,论文对拟建的太平湖大桥桥位区地形地貌、地层及构造等工程地质环境进行了详细研究,在此基础上,论文结合区域资料对桥位区异常发育的北西向优势结构面的形成机制进行了分析,认为其发育与桥位区南东侧黄山穹隆的隆升形成的放射状裂隙有直接关系。数值分析表明,在大桥荷载作用下,桥基变形小,满足建桥要求。Abstract: Through the systematic investigation with a lots of drillings, the paper has a detailed study on the topograph, strata and structural geology in Taipinghu bridge region. Based on the work, the paper presents that the preferred structural plane formation is related with Huangshan vault uplift (forming NW the radial crack) to southeast Under the engineering load, the deformation of the bridge basement is very small, therefore, it is suitable for bridge construction.
