Some Problems of Deep Foundation Pit Supporting System in Soft Ground

摘要

Because there are thick soft strata in coastal area, only one supporting measure is not enough to support the deep foundation pits, it is often necessary to use several supporting methods. After successful application of some engineerings, the supporting system combined with piles, ring beam and anchors has been proved to be effective in solving the supporting problem of deep foundation pits in coastal geology condition. This paper discusses some problems in the design of this kind of supporting system, such as the calculation analysis of piles and ring beam supporting structure, the stiffness match of anchor with ring beam supporting structure and the hydraulic pressure in soil etc.
