摘要
本文先用一般方法计算中山河闸的桩基承载力,再用abaqus三维有限元软件将地基、闸室、灌注桩整体建模来计算整体结构的位移场和应力场,结合中山河闸工程实际情况分析闸室结构的安全性态。分析结果表明:中山河闸的桩基承载力、闸室结构的承载力均满足要求,并且采用abaqus有限元方法能更精确的反应结构强度和位移状况。
In this paper,the general method was fist used to calculate the bearing capacity of pile foundation of Zhongshan River sluice,and then the overall model of the foundation,chamber and filling pile was established to compute the displacement field and stress field with the three-dimensional finite element software ABAQUS.Combined with the actual situation of Zhongshan River sluice Project,the safety behavior of chamber structure was analyzed.The results showed that the bearing capacity of pile foundation and chamber structure of Zhongshan River sluice all satisfied the demand,and the ABAQUS finite element method could be used to reflect the structural strength and displacement state more accurately.
