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。
In the case of large differences in rock joint development and rock permeability, it is not possible to use a uniform pressure-dissipation test program to conduct tests. Instead, different test methods are used according to the different permeability of bedrock. The corresponding analysis method, in order to obtain the most accurate formation hydrogeological data. According to the infiltration ability from strong to weak choice of the order of the test method is the first rainfall head test, Lu capacity test, pressure water - dissipation test, pulse test. The results show that comprehensive hydrogeological survey methods can more accurately investigate and evaluate the permeability and integrity of underground rock mass.
