摘　　要：在岩体节理发育程度不同和岩层透水能力差异大的情况下,不能采用统一的压水-消散试验程序进行试验,而是根据钻孔基岩的渗透能力的不同选用不同的试验方法,并运用相应的分析方法,以求得最为准确的地层水文地质数据。根据渗透能力由强到弱选择的试验方法次序是降水头试验、吕容试验、压水-消散试验、脉冲试验。结果表明,综合水文地质勘察方法能够更准确地对地下岩体的渗透性及完整性进行调查和评估。Under the big differences with development degree of rock mass joints and permeability of rock layer, unified inject-fall test can not be used. According to different permeability of rock mass in berehole, different test and analysis method should be chosen in order to get exact hydrogeological data. According to permeability of rock mass from strong to weak, test methods are conducted in sequence falling-head test, Lugeon test, inject-fall test, standard short duration tests, long duration tests, pulse test. As a result, comprehensive hydrogeological investigation can truly investigate and evaluate the permeability and integrity of rock mass.
