采用三维有限元计算了岩基情况下桩基托梁挡土墙结构托梁上的应力分布,提出了托梁上应力分布的新假设。通过对计算结果的分析比较,指出了在托梁设计中应注意的问题。
Three-dimensional finite element method is used to calculate the stress distribution on the pile-girder retaining wall structure joist in the condition of rock foundation, and the new hypothesis of stress distribution on the joist is proposed. Through the analysis and comparison of calculation results, the problems that should be paid attention to in the design of joist are pointed out.
