基于等效截面法的TRD围护墙变形研究

Research on Deformation of TRD Retaining Wall Based on Equivalent Section Method

为简化计算和分析围护墙的变形,以等厚度型钢混凝土搅拌墙为例,探索一种新的方法.该方法利用静力学中的力平衡原理,将TRD围护墙中的型钢以及混凝土这2种材料等效为1种规则截面的第3种材料.利用有限元软件建立不同墙厚、型钢间距及型钢规格下的4组模型,并对其进行对比分析后表明利用原始参数建立模型得到的结果与利用等效参数建立模型得到的结果相吻合.在进行TRD围护墙变形计算时,将该方法运用其中,可使计算更加简便.

A new method is explored in this paper to calculate and analyze the deformation of retaining wall.This method adopted is to use the force balance knowledge in statics to equivalent the steel and concrete materials in TRD enclosure wall to the third material with a regular cross section.It compared and analyzed four sets of models with different wall thickness,section steel spacing and section steel specifications established by finite element software.Finally,it is concluded that the results obtained by establishing the model with original parameters are consistent with those obtained by establishing the model with equivalent parameters.Therefore,this method can be applied to make the calculation easier when calculating the deformation of TRD retaining wall.
