摘要
利用黏弹性理论对单边自由的固支岩板的黏弹性力学行为进行了分析研究,重新导出了相空间中 黏弹性参数的变换关系式,并利用此式建立了单边自由的固支岩板的广义Kelvin黏弹性分析格式,将其应用 于某层状岩体洞室顶板的变形特性分析.计算表明,其与实际勘察结果比较接近,可供工程实际应用参考.
Based on viscoelastic theory, the behavior of a viscoelastic fixed rock plate with one free boundary is studied, and the new transform relations of viscoelastic parameters are derived in the Laplace space. The analytic formulas of the generalized Kelvin model are obtained for the fixed rock plate with one free boundary by using the new transforms, and the formulas are used to analyze the deformation of some rock cavern roof. The calculating results agree well with practical measurements and can be used for engineering reference.
