| 摘 要： | 以深厚冲积层千米深立井10组不同层位冻结壁段为计算模型,利用FLAC数值分析得到考虑冻结壁厚度、冲积层深度、开挖段高、井帮暴露时间和井筒开挖半径等因素在内的冻结壁井帮最大径向位移的50组数据。对数据进行回归分析,得到冻结壁井帮最大径向位移计算公式,比较结果表明公式计算值与实测值吻合。

| Abstract: | Based on designing frozen soil wall in deep alluvium in thousand metre vertical wall, making use of FLAC mathematic simulation software after selected ten samples from exceeding 400m depth as calculation model, the maximum radial displacement was obtained. The factors affecting it such as frozen soil thick ,height of deep alluvium, segment height,exposure time and excavated radius were utilized. The mathematic formula was acquired with regression analysis through fifty datas, and detected with in-situ measurement data, which the result of two type coincided. |
