【摘要】 笔者对岩溶地区桩的稳定性研究现状进行了归纳总结,将垂直承载桩的稳定性问题分为溶洞顶板稳定性问题及覆盖岩溶临空面稳定性问题,将水平承载桩的稳定性问题分为主动区、被动区及桩端下部存在溶洞时的稳定问题及覆盖岩溶临空面稳定性问题。并分别对上述各类问题进行论述,分析了现有研究成果所解决的问题,指出了下一步的研究方向,为广大学者在岩溶地区桩的稳定性领域的研究工作提供参考。更多还原

【Abstract】 The authors summarize the research status of pile stability in karst area, divide the stability problem of vertical bearing pile into the stability of karst cave roof and the stability of overburden-karstic free face, and divide the stability problem of horizontal bearing pile into the stability of piles when karst caves exist in the active zone, passive zone, the bottom of the pile tip and the stability of overburden-karstic free face. The problems mentioned above are discussed separately, the problems solved by existing research results are analyzed, and the next research direction is pointed out, in order to provide reference for the research work of scholars in the field of pile stability in karst area.更多还原
