摘要
基于变形控制原则的桥梁设计方法,可以在保证桥梁荷载的基础上,合理减少桥梁的桩基数量,为桥梁施工节约相应成本。本文以陡坡地段的桥梁桩基设计为例,利用离散微积方程,构建桩基础设计模型,并对其进行仿真分析。结果显示,提出的桥梁桩基础设计方法,可以大幅度提高桩基设计的准确率,将其最大误差控制在10%以内。同时,通过对桩基础压力的细化分析,可以提高桥梁桩基础设计的准确性。
The bridge design method based on the principle of deformation control can reasonably reduce the number of bridge pile foundations on the basis of ensuring the bridge load,and save the corresponding cost for bridge con⁃struction.This paper took the design of the bridge pile foundation in the steep slope section as an example,used the discrete micro-integration equation to construct the pile foundation design model,and conducted simulation analysis on it.The analysis results show that the proposed bridge pile foundation design method can greatly improve the accu⁃racy of the pile foundation design and control its maximum error within 10%.At the same time,through detailed anal⁃ysis of pile foundation pressure,the accuracy of bridge pile foundation design can be improved.
