Abstract

Since the complexity of the structure of rock itself and the current test conditions is relatively simple, combined with uneven quality of test personnel, rock mass mechanics parameters are necessarily inconsistent with the actual situation. Based on grey relation analysis of parameters sensitivity of cavern stability, you can analyze the influence degree of the relative variation of rock mass mechanics parameters on the cavern stability. Taking Dagangshan hydropower Station as an example, considering the rock mechanics parameters elastic modulus, poisson's ratio, cohesion, angle of internal friction disturbance, using sensitivity analysis method for determining a main building around Dagangshan hydropower plastic zone biggest impact is cohesion, angle of internal friction, followed by elastic modulus, poisson's ratio. This provides a theory foundation for the future test staff should pay more attention to rock mass's cohesion, angle of internal friction in acquiring rock mechanics parameters, ensuring the rock mass's accurate cohesion, angle of internal friction, thus indirectly ensure the stability of underground engineering.
