- Scope
- This standard specifies the technical methods and technical requirements for measuring in-situ stress by hydraulic fracturing and core removal methods. It is suitable for the measurement of various rock mass engineering sites that require in-situ stress data. The hydraulic fracturing method is suitable for When the measurement depth is greater than 50 m, the core lifting method is suitable for situations where the magnitude and direction of the three-dimensional principal stress need to be known.
