摘要:
与传统护坡相比,生态护坡强调在满足岸坡稳定性的同时达到修复生态、保护环境的目的。概括了河流岸坡生态护坡的内涵和特点,总结了常用于河流岸坡的生态护坡技术,重点介绍了石笼网生态护坡作为一种柔性护坡方式在国内外研究进展及其在工程中的应用。通过对已有理论和试验的分析,阐明了影响石笼网结构护坡性能的主要设计参数。在此基础上,结合工程中出现的问题,提出需要进一步研究的内容:石笼网结构抗冲刷特性研究、石笼网填石料级配、厚度与抗冲流速关系的研究及石笼网与植被的结合试验研究。通过对石笼网结构的深入研究,以获取更多的理论支撑,进一步优化石笼网结构的设计,更好地指导工程实践。

Abstract:
Compared with the traditional slope protection, ecological slope protection emphasizes the stability of the bank while achieving the goal of restoring the ecology and protecting the environment. This paper summarizes the connotation and characteristics of river bank slope’s ecological protection and the protection technology commonly used in the river bank slope, and mainly introduces the use of stone cage as a flexible slope protection method, and its research progress and application in engineering at home and abroad. Through the analysis of the existing theories and experiments, the main design parameters affecting the slope protection performance of the cage net structure have been clarified. On this basis, considering the problems arising in the project, the topics that need further study are proposed: anti-scouring characteristics of stone cage network structure, the relationship between grading, thickness and impact velocity of rockfill material, and the combination of cage net and vegetation. Through in-depth studies of the structure of the stone cage net, we hope to get more theoretical support, so as to better guide the engineering practice.
Key words:  river bank slope  ecological slope protection technology  stone cage structure  design parameters
