The dipole method is now popular means for S-wave logging. Essential features of this method are explained, emphasizing basic concept based on approximation of the long-wavelength and the far-field. History of my researches concerned is shortly reviewed as background to reach the idea of this method. Short wavelength behavior of the dipole method is simply reviewed. Methods to reject tube wave noise are commented.

인천 남동공단에서 약 9Km 떨어진 해상에 준설, 매립하여 조성된 3만평의 인공섬에 위치한 인천 LPG 수입기지 현장은 인천광역시와 수도권 지역에 민수용 LPG의 안정적인 공급을 하기 위하여 건설되는 LPG저장용 지하동굴 공사 현장이다. 저장 용량은 Propane가스 17만톤($34만5천\textrm{mm}^3$), Butane가스 7만톤($12만5천\textrm{mm}^3$) 이다. 지하저장시설은 대용량의 액화가스를 주변환경을 해치지 않으면서 화재나 전쟁, 지진등 재해로부터 안전하게 보호 하는데 가장 경제적이고 효율적이며, 운전 및 유지 보수 비용이 적게 드는데다 국토의 효율적인 활용과 공사비가 저렴하다는 장점을 갖고 있다.(중략)

Until recently, limestone yield production is mainly depend on geological investigation and boring. In the study seismic and electrical method are applied to calculate the basic data of limestone yield production. the result of geophysical prospecting, the depth of bed rock is approximately 17m. And there is a slightly difference between the limestone layer boundary which is drawn by electrical prospecting method and that of geological investigation.

The KURT (KAERI Underground Research Tunnel) is a research tunnel which is located in KAERI (Korea Atomic Energy Research Institute) site. At KURT, researches on engineering and natural barrier system, which are the most important components for geological disposal system for high level radioactive waste, have been conducted. In this study, we synthesized the site characteristics obtained by various types of site investigation to introduce the geological model for KURT site, and induced the 3-D hydrogeological model for KURT site from the geological model. From the geological investigation at the surface and boreholes, four geological elements such as subsurface weathered zone, upper fractured rock, lower fractured rock and fracture zones were determined for the geological model. In addition, the geometries of these geological elements were also analyzed for the geological model to be three-dimensional. The results from 3-D geological model were used to construct the hydro-geological model for KURT site, which is one of the input data for groundwater flow modeling and safety assessment.
