철도 노반의 지지력 평가를 위한 현장시험법 적용성 연구

초록

The field plate load test a good potential for determining modulus since it measures both plate pressure and settlement. However, because The field plate load test is expensive and takes plenty of time for operation, it is very difficult to figure out the test characteristics of railroad roadbed in detail. For faster and economical operation, the Light Falling Weight Deflectometer(LFWD) have been utilized for estimating the bearing capacity of railroad roadbed. The objective of this study is to determine the relationship between the test(PLT, LFWD) of the railroad roadbed in Korea. The LFWD test for evaluating the strength of railroad roadbed materials produced in Korea are presented in this paper.
