摘　　要：地下空洞给采空区范围内的公路施工建设带来了巨大挑战。以国道丹阿公路黑山村至鸡西段改扩建工程为例,将水泥粉煤灰浆液充填法用于采空区公路路基治理中,制定了科学的工艺流程和施工措施,并对注浆施工过程严格监控,解决了拟建路线后续的地表移动与变形问题,为道路通车后的安全运营提供了保障。The underground cavity brings great challenges to highway construction within the scope of goaf. Taking the reconstruction and extension project from Heishan village to Jixi section of Dandong-Aletai Highway as an example, this paper used cement-fly ash slurry filling method in treatment of highway subgrade in goaf Scientific construction process and measures were adopted and grouting process was strictly monitored and controlled to solve the follow-up surface movement and deformation problems along the proposed road, providing guarantee for the safe operation of the highway after it is opened.
