中小河流治理中雷诺护垫设计方法探讨

Discussion on the Design method of Reno mattress in the treatment of small and medium-sized Rivers

对雷诺护垫设计方法进行了研究,通过河流岸坡护脚的冲刷深度和整体抗滑稳定性要求,计算出雷诺护垫坡脚的长度;考虑流速和波浪因素的影响,综合确定了雷诺护垫的填石粒径和厚度;进而确定出反滤层与地基土界面流速及土工织物孔径,以此总结出中小河流治理工程中雷诺护垫结构设计的一套准则。最后以某中小河流治理工程护岸设计为例,对雷诺护垫的设计过程进行了介绍。

The design method of Reno mattress was studied,according to the scouring depth of river bank slope and the requirement of overall anti-sliding stability,the length of Reynolds cushion foot is calculated,and the rock filling particle size and thickness of Reno mattress are determined comprehensively considering the influence of velocity and wave factors. The design of filter layer determines the interface velocity between filter layer and foundation soil and the pore diameter of geotextile,and summarizes a set of criteria for the design of Reno mattress structure in small and medium-sized river treatment projects. Finally,taking the bank revetment of a small and medium-sized river treatment project as an example,the design process of Reynolds mattress is introduced.
