摘　　要：注浆法是治理公路下伏采空区的传统方法,但注浆范围的界定问题尚未很好解决。文中参照《公路工程质量检验评定标准》中的公路验收指标作为治理效果评价指标,重点分析了合理的注浆宽度与采空区埋深的关系。Grouting is the traditional method for treatment of mined-out area underlying highway,but grouting range has not been defined yet.This paper emphasizes on the relationship between reasonable grouting width and mined-out area buried depth depending on highway acceptance indicator specified in Quality Inspection and Evaluation Standards for Highway Engineering as the treatment result evaluation indicator.
