摘要
新建道路上跨既有道路时,按规范需要对被跨越工程进行涉路项目工程技术评价。结合实际案例,利用ABAQUS有限元软件对新建道路上跨某既有隧道的施工、运营进行全过程数值模拟,得出不同工况下既有隧道的沉降及内力附加值,为其他类似工程提供借鉴。
When a new road crosses an existing road, the engineering technology evaluation of the project to be crossed shall be carried out according to the requirements of the specification. Combining actual cases, this paper uses ABAQUS finite element software to carry out numerical simulation of the whole process of construction and operation of an existing tunnel across a new road, and obtains the settlement and internal force added value of the tunnel under different working conditions, which can provide reference for other similar projects.
