摘要
铁路作为重要的交通运输工具,在国民生活中起着举足轻重的作用,然而铁路的基础建设仍是困扰铁路快速发展的难题。新建、改扩建铁路线工程,总会受到地质条件、既有构筑物的制约,优化线路结构能够保障铁路运输安全。本文介绍铁路线跨箱涵构筑物,通过人工挖孔桩加固路基,以减少铁路线跨箱涵地段的沉降,同时,桩基础能够补强箱涵构筑物的结构强度,实事证明该结构设计方案切实可行。同时,本文运用Abaqus有限元软件对桩基础进行模拟分析,验证桩基础补强铁路线路基的作用。
As an important means of transportation,railway plays an important role in the national life.However,the infrastructure construction of railway is still a problem that perplexes the rapid development of railway.The new construction,reconstruction and expansion of railway lines are always restricted by geological conditions and existing structures.Optimizing the line structure can ensure the safety of railway transportation.This paper introduces the structure of box culvert crossing the railway line.The settlement of the section of box culvert crossing the railway line is reduced by strengthening the subgrade with manual digging piles.At the same time,the pile foundation can strengthen the structural strength of the box culvert structure,which proves that the structural design scheme is feasible.At the same time,this paper uses ABAQUS finite element software to simulate and analyze the pile foundation to verify the role of pile foundation in strengthening railway line foundation.
