桥梁桩基群桩效应分析

Analysis of Pile Group Effect of Bridge Pile Foundation

山区道路修建过程中,桥梁桩基施工尤为重要。桥梁桩基结构受外力影响较大,主要受到桩顶转递的竖向荷载、斜坡对桩基的剪切作用。在稳定性不足地段还应设置群桩基础。论文针对群桩基础进行了以下分析:通过实际工程对群桩基础的理论计算结果和数值模拟结果进行了分析,并对2种方法的结果进行了比较分析,分析结果表明,理论计算结果较为保守。该结论为桥梁桩基群桩效应研究提供了理论分析和参考。

In the process of mountain road construction, the construction of bridge pile foundation is particularly important. Because the structure is greatly affected by external force, it is mainly affected by vertical load transferred from pile top and shear action of slope on pile foundation. Group pile foundation should also be set in areas with insufficient stability. Therefore, this paper analyzes the following contents: the theoretical calculation results and numerical simulation results of group pile foundation are analyzed through practical engineering, and the results of the two methods are compared. The compare results show that the theoretical calculation results are conservative. Therefore, this paper provides theoretical analysis and reference for the research of this subject.
