摘　　要：路基开裂是道路工程中较常见的病害,特别是软基高填路段。通过对某项目软土路基开裂的原因分析,发现主要是由于处理后的复合地基抗剪强度不满足要求所致,据此提出3种加固处理方案,择优选择换填轻质土方案。实施结果表明,工程效果良好。The roadbed cracks is a common problem in road engineering,especially the soft high fill sections.The causes of soft soil subgrade cracking of a project is analyzed,which is mainly due to thatthe shear strength of composite foundation after treatment does not meet the requirements.Three kinds of reinforcement schemesare put forward andcompared,the best replacement scheme of lightweight soilischosen.After the implementation of the project,the project has achieved good results,which provides a reference for similar projects.
