Research on Repeatability of Karst Water Burst Flood and Stability of Long-Hole Grouting in Long and Large Tunnel

Abstract:

The concept of karst water burst flood is first proposed in Maluqing tunnel construction. The paper analyzes repeatability intermittent hysteresis of karst water burst flood. Work out the plan that long-hole grouting based on these characteristics, and evaluat the safety and stability of water stop cement according to Darcy’s law and site actual measurement.
