摘要
组合桩结合两种桩型的优点,扬长避短,可以达到提高承载力、减小桩顶沉降、降低造价的目的。越来越多的组合桩已广泛应用于工程实践中,取得了良好的经济效益和社会效益。通过对国内外组合桩的试验研究和应用情况进行较为系统的总结和分析,加深对组合桩的认识,为组合桩的推广提供较为完整的实践和理论依据。最后提出了组合桩的优点和缺点以及今后的发展方向。组合桩是一种优越的桩型,值得推广应用。
Composite pile is a new type of pile by combination of two kinds of piles, which could draw advantages and avoid weaknesses, so could achieve the purpose for raising the carrying capacity and reducing the pile top settlement and cost. More and more composite piles have been widely used in engineering practice, and good economic and social benefits have been achieved. In order to deepen the understanding of composite pile, the systematic summary and analysis are carried out for the domestic and foreign research and application of composite pile, thus to provide the more comprehensive practices and theoretical basis for promoting the composite pile. Finally, some advantages and disadvantages of the composite pile are put forward, and the future development of it is also pointed out. The composite pile is a superior type of pile, which is worth popularizing and applying.
