摘要
珊瑚礁灰岩是一种特殊的岩土类型,由于其物质组成、结构和发育环境的特殊性,导致其具有独特的物理力学特性.文章通过对西沙群岛珊瑚礁灰岩的室内物理力学特性展开试验,设定试验流程,分析珊瑚礁灰岩的纵波波速试验、密度试验、孔隙率试验及单轴抗压强度试验等结果,采用回归分析方法,提出珊瑚礁灰岩岩块密度ρ与纵波波速V_P、孔隙率n与干燥波速V_P以及单轴抗压强度R与岩块纵波波速V_P的回归方程.
Coral reefs calcareous rock, being a special type of rock, has special physical and mechanical properties due to its composition, structure and sedimentary environment. Based on the physical and mechanical characteristics of coral reefs calcareous rock in Xisha Islands, testing process is set up, the results of wave test, density test, porosity test and uniaxial compressive strength test are analyzed, the regression analysis method is adopted, the regression equations of density ρ and wave Vp, porosity n and wave Vp, uniaxial compressive strength R and wave Vp of calcareous rock are put forward.
