Abstract

In this study, the field density test was conducted as a volume conversion factor for the design of the excavation soil of the blasting rock. As a result of the field density test, the average volume conversion factor of rock was 1.001, which was smaller than the volume conversion factor of weathered rock 1.1. In the case of rock filled soil, the causes of the increase and decrease of the volume of the soil are provided by various phenomena. However, the specific techniques such as investigation and test methods are insufficient. Therefore, it was confirmed that the method of field density test is very useful method.

본 연구에서는 암성토의 토공량 설계에 대한 대책방안으로 현장밀도시험을 수행하였으며, 현장밀도시험결과 암성토부의 발파암 평균 체적환산계수는 1.001로서 풍화암의 체적환산계수 1.1보다 작은 값이 나타났다. 이와 같이 암성토의 경우 여러 가지 현상에 의해 토공량의 증감 원인을 제공하고 있으나, 이에 대한 조사 및 시험방법 등 구체적인 기술 등이 부족한 실정이므로 본 연구결과에서와 같이 체적환산계수를 검토하기 위한 조사방법으로 현장밀도시험방법이 매우 유용한 방법임을 확인하였다.
