我国堤防道路研究与技术进展

堤防道路涉及水利与交通2门学科,发挥着防洪和交通运输的双重作用。结合我国近年来堤防道路发展历程,在已建堤防道路工程概况基础上,总结我国堤防道路的建设特点:道路类型取决于地理位置,建设标准不断提高,道路功能逐渐扩展且设计更加灵活。阐述目前我国堤防道路建设在堤路结合形式、设计速度、功能分类分级体系、横断面形式、堤防加宽稳定措施、填筑材料和压实标准、堤基处理、路面防裂、管理和维护机制9个方面的技术进展,指出了仍需深化研究的3个问题,即堤防道路关键设计指标体系、加宽堤防的渗流稳定性和管理办法。

Advances in Research and Technology of Levee Road in China

Involving water conservancy and traffic engineering, levee road plays a dual role of flood control and transportation. In the light of levee roads built in recent years, the development stages and construction features of levee road in China are summarized: road type is depended on location; construction standard continues to improve; road function expands gradually, and designs are more flexible. Furthermore, the technical advances of levee road in China are expatiated in the following nine aspects: the form of combination between levee and road, design speed, function classification and grading system, cross section form, stability measures for embankment widening, filling materials and compaction standard, foundation treatment, pavement crack prevention, and management and maintenance mechanism. Finally, three issues which need further research are pointed out: key index system for design, seepage stability of road widening, and management method.
