摘要

摘要: 基于桩土间相互作用的研究思路,提出了一种能够研究表层劣化对桩承载性状影响的室内模拟试验方法并初步探讨了表层劣化对桩承载性状的影响。试验结果表明,工作荷载作用下的摩擦桩,桩侧表面发生劣化可导致桩的沉降量增加,并可能影响桩的正常使用。

Abstract: Based on the research approaches of the interaction between piles and soils, a laboratory experiment method is proposed to study the effects of skin degradation on bearing properties of piles. The influences of skin degradation on the bearing properties of friction piles are discussed. The test results show that the skin degradation of friction piles under working load can lead to the increase of settlement of piles and may affect their normal function.
