压水试验是测定若层裂隙性和渗透性的最常用的方法之一。用压水试验测定岩层裂隙性和渗透性的指标是单位耗水量、单位吸水量和渗透系数。 单位耗水量指一定试验段中水位每抬高1公尺时的钻孔耗水量。单位吸水量是指在1公尺水柱压力下1公尺长的钻孔试验段中的耗水量。由于单位吸水量
Pressurized water testing is one of the most commonly used methods for determining the fissure and permeability of layers. Water pressure test used to determine rock fracture and permeability indicators is the unit water consumption, unit water absorption and permeability coefficient. Unit water consumption refers to the water level in a certain test section when the water level is raised by 1 meter. Water absorption per unit is the amount of water used in a 1 meter long borehole test section at 1 mW pressure. Due to the unit water absorption
