부분안전계수를 이용한 경사식 방파제의 최적설계기법

Abstract

As there are so many uncertainties associated with using the determinism analysis method in the design of rubble mound breakwater, it is impossible for a designed construction to provide ultimate stability. First of all, due to the uncertainty of Load and Resistance, a safety level concerning the destruction mode of construction must be given. Then, the optimization design should be processed. After all, we can say that it is a more reasonable design method than the design used by the stability rate. In this study, an established design process is accomplished using Hudson`s equation and an economic analysis with the breakwater`s section is also conducted. Hudson`s equation is compared to Van der Meer`s equation. These results are utilized to drop a damage rate, increase the stability of construction, and determine the optimization section of the breakwater.1. 서 론
