【摘要】以某一级公路采空区路基为工程背景，根据勘察结构建立采空巷道的地质模型，利用岩体力学的方法将采空巷道 地质模型转化为力学模型，结合一级公路的荷载等级，分析采空巷道的受力情况，提出采空巷道的稳定的顶板厚度，并与 塌陷充填理论进行对比，分析各方法的适用性。

【Abstract】Taking the goaf Subgrade of a first-class highway as the engineering background,the geological model of the goaf is established according to the survey structure.The geological model of the goaf is transformed into a mechanical model by using the method of rock mechanics.Combined with the load grade of the first-class highway,the stress condition of the goaf is analyzed,the stable roof thickness of the goaf is proposed,and compared with the collapse filling theory to analyze the applicability of each method.
