桩基负摩阻力特性研究探讨

摘要

在桩基工程中,因负摩阻力问题造成工程事故屡有发生,负摩阻力问题相关研究现在越来越受到重视.本文介绍了桩基负摩阻力产生机理及影响因素,简要论述了其研究现状,并探讨了现今桩基负摩阻力特性研究中存在的主要问题.%Engineering accidents often occur due to negative skin friction in pile foundation engineering. The research on problems of negative skin friction has been paid more and more attention. This paper introduces the occurring mechanism and influencing factors of negative skin friction, discusses the present research situation and development of the research on negative skin friction, and probes into the main problems existing in the study on characteristics of negative skin friction in pile foundation.
