剪力键分布密度对支护桩抗浮结构的影响研究

Influence Research of Shear Connector Density on Construction of Retaining Piles Working as an Anti-floating Method

针对利用支护桩抗浮结构中剪力键分布密度的问题,运用ABAQUS有限元软件,将结构视为弹性材料,从而建立了不同剪力键分布密度下结构的有限元模型。研究结果表明:剪力键分布密度对结构构件影响明显;剪力键分布密度应根据实际工程的具体要求来进行确定,考虑到工程要求,可以适当调整。在有严格要求的重要地下工程中,剪力键分布密度建议取1;在抗渗要求不高的地下结构中,满足结构安全的情况下,可以取2或3。

With regard to the shear connector density of retaining piles working as an anti-floating method problems,a finite element analysis model of different shear connector density was established by adapting the ABAQUS software and regarding construction as elastic material.It was shown that:shear connector density have a greater effect on the structural components;more choices can be made according to the actual engineering situations.Considering the effectiveness of projects,the distribution density of shear connectors can be adjusted properly.It is suggested that the distribution density of shear connectors is 1 in the important underground construction with strict requirements.when the underground construction don’t require much in the way of impermeability,the distribution density of shear connectors can equal 2 or 3 after security needs are met.
