既有盾构隧道修复加固技术研究综述

摘要

盾构隧道运营过程中会受损发生病害,对盾构隧道修复加固技术的研究,有利于减少事故发生.根据加固措施进行的位置不同,可将加固措施分为内部加固和外部加固.内部加固可分为内张钢圈加固法、黏贴复合腔体加固法、芳纶布加固法、碳纤维布加固法等;外部加固为侧向注浆加固法等.本文对发展概况及研究进展进行了综述,分析其作用机理和优缺点等,对未来的研究方向提供了一些建议.%Damage occurred during the operation of shield tunnel.The shield tunnel repair rein-forcement technology research, help to reduce the accident occurred.Depending on the location of the reinforcement measures,the reinforcement measures can be divided into internal reinforcement and ex-ternal reinforcement.Internal reinforcement can be divided into inner steel ring reinforcement method , paste composite cavity reinforcement method, aramid cloth reinforcement method,carbon fiber sheet reinforcement method;external reinforcement is the lateral grouting reinforcement method.This paper summarizes the development and research progress,analyzes its mechanism, advantages and disadvan-tages,and provides some suggestions for the future research direction.
