摘　　要：煤炭的大规模开采导致公路下存在大量采空区,采空区的潜在危害性严重威胁公路运营安全。为了应对这一问题,提出了改建公路下伏房柱式采空区受力及形变分析。以淄博市公路改建工程为依托,采集公路下伏房柱式采空区三维形变数据,分解采空区三维形变数据,计算采空区受力,作为分析采空区受力及形变的数据基础。工程实测数据结果表明:采空区受力随倾角与煤层厚度的减小而降低,采空区形变随受力的降低而变小。The large-scale coal mining results in a large number of mined-out areas under the highway,and the potential hazards of mined-out areas seriously threaten the safety of highway operation.In order to deal with this problem,this paper puts forward the stress and deformation analysis of the room-pillar goaf under the reconstructed highway.Based on the reconstruction highway project of Zibo City,the 3D deformation data of the mined-out area with room and pillar under the highway are collected,and the 3D deformation data of the mined-out area are decomposed to calculate the forces acting on the mined-out area,as the analysis of the goat force and deformation of the data basis.The results show that the stress of goaf decreases with the decrease of dip angle and coal seam thickness,and the deformation of goaf decreases with the decrease of stress.
