초록
PEM(Prestressed Earth Method) is a method to minimize lateral movements of the ground generated by progressive excavation and increases shear strength by applying prestresses to the end of earth bolt equipped with a P.C. panel after earth bolt is set up under the in-situ ground. In case of PEM, there are noticeable advantages. First of all, PEM maximizes the utility of the ground because PEM needs less volume of backfill and cutting than other general walls. Second, it's an environmental method possible to garden on the banquette. In this study, the behavioral characteristics of PEM are analyzed and compared with soil nailing system through the measured data of PEM and numerical method using SMAP-2D program and also an increased stability of PEM is evaluated by increasing prestress of earth bolts through the numerical analysis using Slide (ver. 4.0) program.
