排桩、环梁及锚杆联合支护体系在沿海深基坑工程中的应用

Some Problems Of A Supporting System Combined With Piles,Ring Beam And Anchor Bar Used In Deep Excavation Pit Engineering At Coastal Areas

排桩、环梁及锚杆联合深基坑支护体系通过几个工程的成功应用,证明能够较好解决沿海地层条件下的深基坑支护问题。本文对这种支护体系设计中环梁支撑系统计算、水压力计算、岩层面出露于基坑开挖深度内时嵌岩排桩设计等问题进行了讨论。

After successful application in some engineering examples, the supporting system combined with piles, ring beam and anchor bar has been proved to be effective in solving supporting problem of deep foundation pits of coastal geology condition. This paper discussed some problems in the design of this kind of supporting system , such as calculation of ring beam supporting system , water pressure in soil , design of serial piles buried in rock layer , etc.
