Analysis and evaluation on the influence of road span to the existed underground structure

When a new road crosses an existed underground building structure, it is necessary to carry out engineering technical evaluation of the crossing project according to the requirements of the code. Combined with the case, from the design, construction and operation process of the new road spanning the existed underground building structure, the paper analyzes the most unfavorable situation according to different working conditions, analyzes and evaluates the underground structure, so as to provide reference for other similar projects.
