摘要
为了研究深井开采条件下的巷道围岩控制,阐述了深井巷道围岩体中存在的温度场、应力场和应变场的耦合作用,并且用塑性带厚度来表征它们的共同作用;采用正交有限元方法来考察不同参数、不同水平的变化对塑性带厚度的影响。根据正交实验结果,提出了改善深井巷道围岩体稳定性的措施。
Aimed at studying the control of the deep mine adjacent rock, the paper introduces the coupled field of temperature, stress, and strain of deep tunnel adjacent rock and discusses the representation the coupled action by using the thickness of the plastic zone. The paper highlights the application of the orthogonal finite element method to explore the impact of variable levels and the different parameters on the thickness of the plastic zone. The orthogonal experiments result in the equation regression of plastic zone thickness.
