摘要
安全评价分为安全预评价、验收安全评价、安全现状评价和专项安全评价四类。专项安全评价结论通常决定项目的可行性或安全状态。通过2个实例,介绍了ANSYS在采空区稳定性这一专项安全评价中的应用。结论表明,计算模型的正确性决定评价结果的可靠性,力学参数控制评价结果的精确度。三维ANSYS模型能简便、可靠和快速评价采空区的稳定性。
Safety assessment has been classed to four kinds, viz. advance safety assessment, safety assessment checking and accepting, safety assessment of actuality and special safety assessment. The item feasibility and safety state are decided usually by the conclusion of special safety assessment. By two examples, the application of Ansys in safety assessment of abandoned stope stability is introduced. The study results show that the reliability assessed conclusion is chosen by the correctness calculated model, and the precision evaluated conclusion is chosen by the mechanical parameter. And while abandoned stope stability can be estimated reliably and fleetly by three dimension Ansys model.
