Abstract

Recently, interest in Tie-cell wave-dissipating blocks that can compensate for the disadvantages of block-type breakwaters and provide economically effective design is increasing. Tie-cell wave-dissipating block has high activity resistance due to its structure in which each block is held together by a pile. In this study, through the laboratory model experiments, it was possible to confirm the increase in lateral resistance of the Tie-cell wave-dissipating blocks due to the penetration of the piles. The lateral resistance of the piles appeared almost constant regardless of the overburden load of the blocks. The lateral resistance shared by the piles changed depending on the increase or decrease in the lateral resistance of the friction between blocks. In the experiment in which two piles were penetrated, the overall lateral resistance was larger than the case a single pile was used, but the resistance behavior of the piles was different.

최근에는 블록식 방파제의 단점을 보완하고 경제적인 설계가 가능한 타이셀소파블록에 대한 관심이 증가하고 있다. 타이셀소파블록은 각 블록을 말뚝으로 결속한 구조체로 활동저항성이 매우 우수한 특징을 가지고 있다. 본 연구에서는 실내모형실험을 통해 말뚝의 관입으로 인한 타이셀소파블록의 수평저항력 증가를 명확하게 확인할 수 있었다. 그리고 말뚝의 수평저항력은 블록의 상재하중에 상관없이 거의 일정하게 나타났다. 말뚝이 분담하는 수평저항력은 블록과 블록사이의 마찰이 담당하는 수평저항력 증감에 따라 변화하였다. 말뚝을 두개 관입시킨 실험에서는 싱글말뚝을 사용한 경우 보다 전반적으로 수평저항력이 크게 나타났으나 말뚝의 저항 거동은 다르게 나타났다.
