Abstract
The purpose of this study is to estimate the bearing capacity and settlement characteristics of the weathered granite masses, and on the process to achieve the purpose, in the first place, the weathered degree according to the absorption index was examined and reviewed, then plate bearings test in in-situ depth were tested, and finally the result was compared and examined with the result of the existing, estimate method and pressuremeter test. In order to achieve the purpose of this study, a typical area distributed with weathered granite masses, gyeonggi area, was chosen as a sample site for testing, and in the result, it appeared and found out that the more the weathered degree increases when the plate bearing test are tested, the more the bearing capacity decreases a numerical indexes and the more greatly the width of the decrease of bearing capacity increases around the boundary of specific, weathered degrees. Also, In the result from estimating the bearing capacity of weathered granite masses by the existing, suggested formula, it appeared that there is a tendency that the more the weathered degree increases, the more similar the bearing capacity becomes with the result of plate bearing tests.
본 연구는 화강 풍화암반의 지지력 및 침하특성을 평가할 목적으로 수행된 것으로 흡수율에 따라 풍화도를 고찰하고 원위치 심도에서 평판재하시험을 수행하여 이를 기존의 예측방법 및 공내재하시험 결과와 비교, 검토하였다. 이를 위하여 국내의 대표적인 화강 풍화암 분포 지역인 경기
