摘要:
为了研究新型桩-板复合基础受下压荷载时,基础的承载性能及桩土互相作用的机制,应用有限元软件开展了大板基础、单桩基础和桩-板复合基础的下压承载力模拟分析。研究表明:新型桩-板复合基础的荷载-沉降曲线为缓降型曲线,下压荷载作用过程中,桩率先发挥其承载力,当板底地基土达到承载力极限时,桩-板复合基础达到极限承载力。结合现有复合桩基的相关理论,提出了一种基于单桩极限承载力Pu的设计方法,适用于新型桩-板复合基础。
Abstract:
To study the compressive load carrying capacity and the mechanism of interaction of piles and soil when the new plate-pile foundation subjected to compressive load,the nonlinear finite element analysis on slab base foundation,single-pile foundation and new plate-pile foundation were carried out.The results showed that the load-settlement curve of the new plate-pile foundation decreased slowly.During the process of loading,loadcarrying capacity of the pile was the first to reach its limit state.When the loadcarrying capacity of the foundation soil on the plate reached limit state,the new plate-pile foundation reached to its ultimate load carrying capacity.Based on the relevant theory of existing composite pile foundation,a design method on account of single-pile limit load-bearing capacity of Pu was proposed, and was applied to new plate-pile foundation.
