ISO 22282-3:2012规定了根据EN 1997-1和EN 1997-2进行岩土勘测和测试的一部分,钻探在岩石中的水压试验(WPT)的要求。
测试用于调查以下内容:
岩体的水力特性主要由不连续性决定;
岩体吸收能力;
岩体紧密度;
注浆成效;
地质力学行为,例如水力压裂,水力发电
ISO 22282-3:2012 specifies the requirements for water pressures tests (WPT) carried out in boreholes drilled into rock as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.
The tests are used to investigate the following:
hydraulic properties of the rock mass, which are mainly governed by discontinuities;
absorption capacity of the rock mass;
tightness of the rock mass;
effectiveness of grouting;
geomechanical behaviour, e.g. hydrofracturing, hydrojacking.
