摘要:
 以广东省某大型桥梁项目桩基为研究对象,使用Midas GTS/NX数值模拟软件建立了桥梁桩基的数值模型,通过改变模型参数,计算分析了各个参数对桩基变形的影响,分别得到了各模型参数与桥梁桩基沉降,水平位移和桩基轴力值之间的关系,确定了各模型参数对桥梁桩基变形的影响程度,分析结果表明,参数G、K对桩基变形计算结果精确度的影响较大,其中参数G对桩基沉降、水平位移和轴力值的影响都很大,参数K对水平位移影响最大。因此关注对桩基影响程度较大的参数,提高其精确度,对于桩基变形计算非常重要。
Abstract:
 Taking the pile foundation of a large scale bridge project in Guangdong Province as the research object, the numerical model of the bridge pile foundation was established using Midas GTS/NX numerical simulation software. By changing the model parameters, the influence of each parameter on the pile foundation deformation was calculated and analyzed. The relationship between each model parameter and the settlement of the bridge pile foundation, horizontal displacement and the value of the pile foundation axial force determines the degree of influence of each model parameter on the deformation of the bridge pile foundation. The analysis results show that the parameters G and K have a great impact on the accuracy of pile foundation deformation calculation results. Parameter G has great influence on the settlement, horizontal displacement and axial force value of pile foundation, and parameter K has the greatest influence on horizontal displacement. Therefore, it is very important to pay attention to the parameters that have a greater impact on the pile foundation and improve its accuracy for the calculation of the pile foundation deformation.
