Abstract

- We detect three kinds of weak zones of rock mass in the rotary-percussive instrumented drilling process.
- We propose a new analysis method-full drilling analysis for weak zone characterization.
- We summarize the corresponding drilling responses to the three kinds of weak zones.
- We verify the weak zones determined by DPM methodology by grouting test.
