摘要

随着城市地下综合管廊逐渐向深埋覆盖，以及管廊运行复杂性的增加，其安全性能也越来越受到重视。针对于随着内在压力及外部应力而引起的城市地下管廊不稳定变形，本文提出了一种基于极值理论的修正线圈法，通过补正管廊的稳定性，来抑制管廊的变形，并通过实验验证了设计效果。

Abstract

With the increasing of cover depth and the complexity of operation of urban underground pipelines, the safety performance has been paid more attention. Aimed at the instability deformation caused by inner pressure and external forces due to the urban underground pipeline, this paper proposed a modified coil method based on the extreme value theory to correct the stability of the pipeline to suppress the deformation, and validated the design effect through experiment.
