近海抛填石区域深基坑支护技术的探讨与实践

Technology Research and Practice of Supporting-systems For Deep Foundation Pit in Coastal Riprap-filling Region

本文通过厦门近海抛填石区域某深基坑工程,在比选常用支护及止水方案后,采用冲孔咬合桩支护止水方案。实践表明,在类似地质及水文条件下,冲孔咬合桩能较好地适应该地层的深基坑工程,同时,相对其他支护方式其造价低廉,是一种在类似工程中值得推广的围护方式。

This paper is a description of bite--piles in low as the retaining and protecting for foundation excavation and curtain for cutting off water, which is in a deep pit of the coastal riprap--filling region of Xiamen by the careful selection. The practice has proved that in a similar geological and hydrological conditions bite--piles in row would be a best supporting system for the excavation works of the deep pit, which costs lower compared to the other retaining and supporting systems for foundation excavation, that should be promoted in a project which is in a similar geological and hydrological conditions.
