【摘要】 提出了基于突变理论隐伏溶洞与隧道间安全距离研究方法,采用突变理论评价隐伏溶洞与隧道间岩层的稳定性,通过研究隐伏溶洞与隧道间岩层系统的总势能,建立岩层系统失稳的突变模型,推导出了隐伏溶洞与隧道间岩层突变失稳判据、失稳力学条件和安全距离计算公式,并用工程实例进行了验证。更多还原

【Abstract】 Based on the catastrophe theory,a research methods of safe distance between concealed karst cave and tunnel is put forward.The stability of rock stratum between concealed karst cave and tunnel is evaluated by the catastrophe theory.The catastrophe mode of rock strata system destabilization is established through the research of rock stratum total potential energy between karst cave and tunnel,then the safe distance calculation formula(contains instability mechanical conditions and instability criterion)between concealed karst cave and tunnel are deduced,which is veried by engineering example.更多还原
