Stability evaluation and microseismic monitoring around Large Underground Oil Storage Cavern in Over-stressed Rock Mass

  • 발행 : 2005.04.01

초록

Brittle failure has been detected in over-stressed rock mass during the construction of oil storage cavern. The main characteristics of stress induced brittle failure of the site are introduced. Various evaluation and measures are sought to stabilize the over-stressed rock mass. The major results from numerical analysis of the cavern are presented, and from current microseismic monitoring to detect hazard from brittle failure are presented.
