彈性波測量에 의한 地下貯藏施設의 地下構造調査에 關한 硏究

A Study on the Underground Structure of Underground Storage Cavern by Seismic Surveying

국토의 이용을 극대화하기 위한 地下貯藏施設의 基礎調査에 物理探査方法중 彈性波測量을 이용하면 地下岩盤 조건을 규명하고 空洞의 位置를 선정할 수 있다. 本 硏究에서는 岩盤의 彈性波速度 및 低速度带의 分布를 分析하여 岩盤 연약대를 파악하므로써 地下施設物 설치의 타당성 결정에 한 技法을 제시하는데 의의를 두고 있다.

The condition of underground basic rock and the location of cavern site can be found by means of seismic surveying is one of the physical exploration methods by which the prelimirary investigation of underground storage constructions are made in order to maximize the use of a land. This study is valuable in the point of showing a method for the decision of the property of a underground facilities estabilishment, by analying the elastic wave velocity and the distribution of a lower velocity zone and by grasping the weak zone of the basic rock.
