In this paper, the tests of the core material＇s influence in rubble mound breakwater on wave propagation are carried out. The relations among the transmitted wave height, incident wave element, and breakwater width are discussed. The calculation formula is obtained. The test results show that different core materials have obvious influence on wave propagation.展开更多

文摘On the basis of Betti's theorem,the constitutive relation of multi- crack rockmass which considers the effect of crack-closure is developed in this paper. Meanwhile,based on mathematical elasticity,the paper gives an analytical formula for the compression transmitting coefficient and the shearing transmitting coefficient. A damage evolution equation of rock-mass is presented and an engineering application is given as well.
