摘要
论述了长短桩复合地基的作用机理,在分析长短桩复合地基承载力和沉降计算方法的基础上提出长短桩复合地基的优化设计,并结合工程实例介绍长短桩复合地基的设计计算、施工技术和处理效果.实践证明,长短桩复合地基能充分发挥桩间土、短桩和长桩三者的潜能,有效提高地基承载力和减少地基沉降,其应用前景广阔.
This paper expounds the mechanism of long-short-pile composite foundation.Based on the analyses of the bearing capacity and settlement calculating methods concerning long-short-pile composite foundation,an optimization design is proposed.Moreover,some engineering cases are used to demonstrate its design calculation,construction technique,as well as treatment effects.The engineering practice indicates that long-short-pile composite foundation can make full use of the potentials of soil and long-and-short piles,thereby increasing the bearing capacity and reducing settlement of foundation.Accordingly,this design has broad application prospects.
