加劲水泥土搅拌桩承载力性状的有限元分析
Finite element analysis of loading capability of cement-soil mixing piles
【摘要】 文章基于加劲水泥土搅拌桩现场试桩静载试验,采用大型有限元分析软件ANSYS对加劲水泥土搅拌桩模型和灌注桩模型进行了分析和研究。数值计算结果表明,通过合理的参数设定和接触模拟,试验和模拟的Q-s曲线吻合较好;加劲水泥土搅拌桩的承载力大于相同尺寸的灌注桩。分析结果为进一步揭示加劲水泥土搅拌桩的荷载传递机理提供了新的技术手段和依据。
【Abstract】 On the basis of on-site static loading tests of cement-soil mixing piles,this paper analyzes the cement-soil mixing pile model and the grouting pile model by using the finite element analytical software ANSYS.The analysis result shows that Q-scurves of the test and those of the simulation are pretty consistent by setting reasonable parameters and contact simulation.Besides,the loading capability of the cement-soil mixing pile is bigger than that of the grouting pile in the same size.The analytical conclusions offer a new technological means and proof to further support the loading transmission mechanism of cement-soil mixing piles.
【Key words】 cement-soil mixing pile; core pile; static loading test; numerical simulation;
