Abstract
<p> In developing countries, there is a breakwater or groin which employs the concrete cellular caisson with filled stones covered by the concrete blocks as economical type of structure. The cover concrete blocks are often just put on filled stones without sealing concrete to consider the instability of the concrete cellular caisson due to uplift force. On the other hand, there is a possibility that the cover concrete blocks are sometimes moved by wave action. It is quite few to study the stability of concrete block at the water surface level. In this study, physical model test using 2-dimentional flume was carried out to know the difference on stability of cover concrete blocks due to difference of water level and type of blocks. Furthermore, measurement of wave force using the 3-component load cell was conducted to know the relation between acting wave forces and stability of cover concrete blocks. It was known that stability is increased by increasing hole rate of block or making surface of block slope.</p>
