前言一般地讲,渗流的时间依存性和孔隙堵塞机理是通过室内试验或在附近现场试验就可了解的现象。并实用上数量不能忽略不计。水在土和岩石这种多孔介质中渗透时,其中溶解的浮游混浊物质会堵塞孔隙,或者被吸附着,而使流速减慢,同时时间也随之减慢。特别在岩石中渗透的情况下这种现象更为明显。 Preface Generally speaking, the time dependence of seepage flow and the mechanism of pore plugging are phenomena that can be understood through laboratory tests or near field tests. And practical quantity can not be ignored. When water permeates porous media such as soil and rock, dissolved dissolved opacity can clog the pores or become trapped, slowing the flow rate and slowing down the time. This phenomenon is even more pronounced, especially when infiltrated in rocks.
