摘要
近年来,随着人们安全意识和环保意识的增强,河道治理要求兼顾河道防洪与生态景观。本文对河道梯形断面、矩形断面、复式断面3种断面形式进行比较,并选取了混凝土护坡、砌石护坡、石笼护坡、土工植生袋护坡、草皮护坡5种护坡材料进行比较,以新河为例,根据河道周边现有建设、规划情况,综合考虑防洪安全、生态景观要求以及工程投资等因素,选取合适的河道横断面。
In recent years,river reconstruction requires both flood control and ecological landscape with the enhancement of people’s awareness of safety and environmental protection.In this paper,the trapezoidal section,rectangular section and compound section are compared,and five kinds of slope protection materials,concrete slope protection,masonry slope protection,stone cage slope protection,geotechnical planting bag slope protection and turf slope protection are selected for comparison.Taking Xinhe River as an example,according to the current construction and planning situation around the river,the appropriate cross-section of the river is selected,considering the factors of flood control safety,ecological landscape requirements and project investment.
