porosity of rock-mass
rock porosity
Examples
- The porosity and permeability measurement of core in net confining stress
覆压下岩石孔隙度和渗透率测定方法 - Based on the mechanism of deformation of rocks , porosity - depth curves of rocks can be divided into tow periods as compaction and compression
摘要根据岩石的变形机制，把岩石孔隙度的变化过程划分为压实和压缩两个阶段，岩石压实阶段的孔隙度呈指数规律变化，岩石压缩阶段的孔隙度保持为常数。 - Study shows that these petrophysical parameters will change with pressures , of which rock porosity will affect other parameters ' variations , and permeability has lag - effect during cycling , rising and declining of the pressure
研究表明，岩石物性参数随压力的变化而变化；岩石孔隙度不同，其他参数变化规律不同；渗透率随压力循环升降存在滞后效应。 - Main content in simulation is the spatio - temporal evolution of the set of descriptive variables characterizing tectonic mineralization state under coupling of various processes as following : ( 1 ) variables related to forming and property of ore - forming fluid , such as dissolution rate of minerals ( include metal minerals ) in rock , concentration and saturation of aqueous species in fluid , temperature , pressure , and ionic strength etc . ; ( 2 ) variables related to structural deformation and fluid flow , such as stress , deformation rate , fracture network , porosity , fracture permeability ; ( 3 ) variables related to precipitation and mineralization , such as nucleation rate of gangue and metal minerals , accumulation precipitation of various minerals , etc . ; ( 4 ) spatio - temporal coupling relation of various variables above , such as the coupling relationship between spatio - temporal evolution of fracture permeability and flow and focus of fluid and ore - forming
模拟的主要内容是在各种过程耦合作用下，以下描述构造成矿体系的主要变量的时空演化：与成矿流体的形成和性质有关的变量，如地层中矿物（包括成矿物质）的溶解速率、流体中各组分的浓度与饱和度、流体温度、压力、离子强度等；与构造变形和流体运移有关的各变量，如应力与变形速率、岩石孔隙度、构造（断裂）渗透率等；与沉淀成矿有关的变量，如矿物（金属矿物和脉石矿物）的成核速率、各矿物的沉淀量等；上述各有关变量间的时空耦合关系，如断裂渗透率时空演化与流体流动、汇聚和成矿的耦合关系等。 - Can influence directly the velocities of compressive wave and shear wave of rock . commonly , the higher the content of carbonate in rock , the higher the velocity of compressive wave and shear wave ; the higher the mud content , the lower the velocity of compressive wave and shear wave ; the higher the porosity of rock , the lower the velocity of compressive wave and shear wave ; the more compacted the rocks , the higher the velocity of compressive wave and shear wav
6 )岩石组成和孔隙度等岩石内部因素均可直接影响岩石的纵横波速度，一般说来，岩石中碳酸盐含量越高，其纵横波速度越高；而泥质含量越高，其纵横波速度越低；岩石孔隙度越高，其纵横波速度越低，岩石密度越大，其纵横波速度越高。
