Abstract

In 2005, Urban railway seismic design was introduced in Rep. Of Korea, and many studies on seismic performance evaluation and reinforcement methods were conducted. In accordance with the Enforcement Decree of the Earthquake Disaster Countermeasures Act issued in March 2009, during April 2010 to October 2013, some of local governments established detailed evaluation and reinforcement measures for seismic performance of the urban railway underground structure. Afterwards, the seismic performance reinforcement of the existing urban railway structures was conducted for the sections that a long period of used until the end of 2018, and the reinforcement works are carried out by various methods using the previously studied methods. However, various reinforcing materials and construction methods using have been studied, but the classification research on the construction methods currently applied to reinforcement construction of urban railways is insufficient. The purpose of study is to analysis the cases currently applied to seismic reinforcement construction and to show the characteristics of each construction method, the reasons for its application and problems.

국내 도시철도는 2005년 내진설계가 본격적으로 도입되었으며, 내진성능평가 및 보강방법에 대한 많은 연구가 이루어졌다. 2009년 3월 공포된 지진재해대책법 시행령(현 지진화산재해 대책법 시행령)에 따라 2010년4월~2013년10월까지 일부 지자체에서 도시철도 지하화 구간의 내진성능 상세 평가 및 보강방안을 수립하였다. 그 후, 2018년 말까지 공용기간이 오래된 구간에 대하여 기존 도시철도의 내진성능 평가를 수행하였으며, 기 연구된 방법을 적용하여 다양한 공법으로 보강공사를 시행하고 있다. 그러나 다양한 보강재료과 이를 사용한 공법이 연구되었지만, 현재 도시철도 보강공사에 적용되고 있는 공법에 대한 분류 실태연구는 미비하다. 본 연구의 목적은 현재 도시철도 내진성능보강 공사에 적용중인 사례를 분석하여, 공법별 특징 및 적용 사유와 문제점을 제시하는데 있다.
