路基病害整治成功与否和设计质量密切相关。而成功的整治设计必须遵循正确的设计程序和原则。为提高整治设计质量,提出了设计前期应开展收集资料、现场勘察和综合分析等工作,确定整治措施时应遵循注重排水、因地制宜、方案比选和综合治理等设计原则,并结合实例阐述了设计原则的重要性及应用方式。 Subgrade disease remediation success or not and design quality are closely related. Successful remediation design must follow the correct design procedures and principles. In order to improve the quality of renovation design, this paper put forward that the design information should be collected early in the design, site investigation and comprehensive analysis and other work. When determining the remediation measures, the design principles should be followed, such as drainage, local conditions, comparison and selection of projects and comprehensive management, The importance of principle and its application.
