浅谈水源保护区高等级公路的设计

论述了水源保护区高等级公路的设计方法。在勘察设计中要对环境保护、水土保持、水源质量保护、工程质量和技术经济等进行全面综合考虑。这其中选择合理的平纵面线型对环保的关系最大 ;通过弃、借土施工 ,再造耕地也是一种较好选择。此外 ,对路面排水进行集中沉淀处理。

This paper discusses the design methods of high-grade highway in water source protection area. Environmental protection, water and soil conservation, water source quality protection, engineering quality, technologies and economies should be considered comprehensively during survey and design. Reasonable selection of plane and longitudinal profile alignment is the most important thing related to the environmental protection. Rebuilding cultivated land shall be also a good choice through spoiling or borrowing soil construction. In addition, centralized pavement drainage treatment or laying of cement concrete pavement etc. are effective high-grade highway design ways suitable for water source quality protection.
