摘要

针对黄土丘陵区山坡道路侵蚀问题，提出了以工程措施和林草措施相结合的山坡道路防蚀工程配置方案、布设原则等，包括工程措施中路面起拱，路边布设蓄水池、蓄水窑窖和截水沟等配置方案和路面种草的草种选择。多年野外实地调查与路面路段监测的结果表明，工程示范路段蓄水池、窑窖和植物措施的综合配置使山坡道路侵蚀模数减少了40%～82%。植物措施示范路段在次暴雨强度下较裸露地面道路侵蚀模数减少了58%～70%，径流减少了50%～69%。路面起拱、蓄水槽、窑窖、截水沟、植物措施的综合配置可以有效地防止山坡道路侵蚀。

Abstract

Aimed at reducing rural road erosion in the loess hilly region

some engineering measures and biological measures were initially proposed. The engineering control measure design was outlined here

which includes arching center road

blocking and cutting road flow by pond

water storage cellar

and cut-off ditch along road side. Some grasses suitable to road surface planting were also selected. To evaluate the effect of the road erosion controlling designs

several road sections were taken to monitor road erosion for several years. Results showed that intercepted sediment volume from the section with integrated engineering measures was a decrease of 40%～82% compared with no protective measure section. In grass-covered section

erosion modulus was decreased by 58%～70% and runoff

by 50%～69% compared with the bare road. Practice has proved that the integrated conservation measure of water storage tank

cellar

cut ditches

and planting can effectively prevent road erosion.
