摘要:
在地下岩体工程中,无论是软岩还是硬岩,只要岩体受力后的应力水平达到或超过该岩体的流变下限,都将随着时间的增长而发生流变变形。针对深部矿井开采中的巷道支护问题,根据粘弹性理论,在考虑开挖面空间效应的基础上,建立巷道围岩与支护体的耦合作用模型; 在此基础上,根据非线性最优化设计原理,建立巷道耦合支护的最优化设计模型。通过算例分析了支护时间、支护体厚度等因素对巷道围岩和支护体稳定性的影响以及对支护设计方案的影响。结果表明,巷道围岩的稳定性与支护时间、支护体厚度等因素密切相关。巷道位移随着支护时间的增大以及支护体厚度的减小而增大; 支护体受力随着支护时间的增大以及支护体厚度的增大而减小。当支护体不发生破坏且巷道位移小于某一临界值时,支护体厚度随着支护时间的增大而先减小后增大。
Abstract:
In the underground rock engineering,the mechanical properties of surrounding rock mass exhibits time-dependent,as long as the rock mass stress level reaches or exceeds the rock rheological limit.In view of the roadway problems of underground mining on the soft rock roadway,based on the theory of viscoelasticity,a model of coupling action between rock and supporting body is built with considering the spatial effect of excavation face.On this basis,based on the theory of nonlinear optimization principle,an optimization model of roadway support is established.The influences of the support time and the thickness of the supporting body on the deformation are analyzed,and the optimal design parameter of the roadway support is discussed in detail by a case study.The results show that support time and the thickness of the supporting body have a certain impact on the deformation.With increases roadway support time and increases supporting body thickness,the displacement increases.When the supporting body is safe and the roadway displacement is less than a critical value,the thickness of the supporting body decrease firstly with the increasing of the support time,and increase later.
