地铁桩基托换施工技术措施分析

The subway construction technology of pile foundation underpinning measures analysis

随着我国城市化进展脚步加快,城市的交通负荷日益增大,为了应对这个困扰我们的难题,国内的主要城市纷纷加入了对地铁交通的建设队伍中。城市地铁轨道的修建基本都在地下开展,因此,在地铁的修建过程中,都无法避开城市原有的建筑物,地铁桩基托换技术应运而生,并得到了广泛的推广。本文从理论上分析了地铁桩基托换的施工技术措施,将理论与实际工程案例结合并进行探讨。

With the accelerated pace of urbanization in China,the traffic load of the city is increasing day by day.In order to cope with this problem,the major cities in China have joined in the construction of the subway transportation.The city subway construction in basic underground development, therefore,in the process of subway construction in the city,can not avoid the original buildings,subway pile underpinning technology came into being, and has been widely promoted.This paper analyzes the construction technology measures of the pile foundation underpinning in theory,theory and practical engineering case are combined and discussed.
