터널 인접구조물의 부등침하 억제를 위한 마이크로파일의 적용에 관한 연구 

A Study on the Application of Micropiles for Control of Differential Settlement at the Surround of Structure on the Soft Ground Tunnelling 

[ 초 록 ]

When building a variety of tunnels, in the central area of a city, there is a large range of opinion on the issue that the safety of many structures, either below or above the land, in the vicinity of the construction site must be secured according to a particular condition of each site. Therefore, this research tried to overcome the problems created by the above issues and intended to apply the Micro File. By comparing and analyzing the result of numeric measurement with the field instrumentation on stress with Micro File, settlement of earth surface, roof settlement and endurance displacement during the excavation of321 section in the tunnel of Busan subway line 3, the effect of displacement restraint for settlement of the nearby structures by the constructed Micro File was evaluated and the effect on the reinforcement angle and the length of the Micro File was also verified.
