A Study on the Stabiltiy Analysis of Railway Slopes Applying Net type Concrete Block (NTCB) Under Rainfall

Abstract

One of the major slope failures in Korea railways is surface failure. It is based on geological and geographical properties of Korea. There are various types of methods to protect surface slope failures. Performance for each method should be examined beforre construction and it is important to select optimum installation place. In this study, Net type Concrete Block (NTCB) is developed to ruduce surface failure of a slope and also the performance of NTCB is examined by various construction location under rainfall.

Numerical and Probabilistic Study on the Optimal Region for Tsunami Detection Instrument Deployment in the Eastern Sea of Korea

“…Potential tsunami scenarios are used to design future tsunami observation instruments [3], and both numerical modeling and potential tsunami scenarios are required to determine the optimal tsunami instrument deployment [3]. In this study, we used 39 potential tsunami scenarios in which all sources are near the west coast of Japan [9][10][11]. To figure out the optimal region for tsunami observation instrumentation, this study only focused on the potential tsunami scenarios that can affect the east coast of Korea and used in previous studies.…”
