C.G.S(Compaction Grouting System)형성 확인을 위한 탄성파토모그래피 탐사

Abstract

Recently, the number of case that applies the geophysics is increasing to evaluate the basement more accurately and systematically, departing from the fragmentary analysis patterns which depend on drilling, as a effort to the site characterization in the civil engineering and environmental fields. However, the error range is still relatively too wide to get quantitative information about geological features and structures of the basement by just geophysical survey in the engineering fields which requires high resolution for the shallow. It's borehole geophysics that overcomes the limitations. In this study, we are adapted tomography of method of crosshole as widely used investigation methods. The purpose of this study is at first to develop various strategies of practical use to overcome forming C.G.S. bulb problems occurred in the tomographical applications. In the edition, approach to the tomography is employed to be well adapted for use various scanning geometry.
