비개착 추진공법에서 관의 형태에 따른 축소모형 융기 및 침하 실험분석

In this study, a non-open cut method using a round or square pipe which has been commonly employed In Korea was experimentally evaluated and the behavioral features resulting from the friction while the pipe is penetrated into the ground was identified through the scale model test. To that end, a test device was fabricated by type of penetration pipe, by which the surface displacement caused by surrounding friction resistance was monitored. To simulate the settlement and heaving by excavation stage, the test was conducted based on generalized friction condition and surface displacement and the result therof was compared and analyzed, considering the type of penetration pipe.
