由于“土塞”的存在,开口管桩的承载机理比闭口管桩更加复杂。为了确定开口管桩极限承载力,本文根据前人所作的工作,简化了管桩承载力计算中的若干参数,并结合莫尔-库仑定律,提出了一种能够在粘土中计算开口管桩极限承载力的简便方法。同时在实例中,通过与其他承载力计算方法相比较,验证了本文方法的有效性,从而能够更方便地应用于工程实践。 Due to the existence of “soil plug”, the open pipe pile bearing mechanism is more complicated than the closed pipe pile. In order to determine the ultimate bearing capacity of open pipe piles, according to the previous work, this paper simplifies the calculation of pipe pile bearing capacity of a number of parameters, combined with the Moore - Coulomb law, proposed a clay pipe can calculate the limit of open pipe piles A simple way to carry capacity. At the same time, compared with other calculation methods of bearing capacity, the effectiveness of the method in this paper is verified, which can be more easily applied to engineering practice.
