Abstract:
Nowadays, more and more attentions have been focused on the eco-environmental protection of the civil works, and the ecological engineering techniques for the side-slope protection works have been widely applied to the roads, embankments, urban hydraulic projects and so on. However, in many cases, the ecological slope protection technology can not meet the requirements of the engineering design. The turf reinforcement mat (TRM) is one of the side-slope protection forms combining the geotechnical fabric and reinforced turf with the slope or river banks, which protects the ecological works and significantly improves the strength of the ecological revetment works, and the TRM technology has been gradually paid attention to and has a wide range of application in recent years. By analyzing the development course and research status of the TRM technology, its development course has been divided into three stages: the traditional ecological slope protection, common reinforced ecological slope protection and high performance turf reinforcement mat slope protection. On the basis of this classification, the different structure types and geosynthetic materials of the TRM revetment works are summarized. And the related researches and main conclusions made by scholars at home and abroad on the development course of the TRM revetment are introduced in detail in this paper. Based on the case histories, the engineering application of the TRM technology including its effects in protecting slopes, reducing soil and water losses and improving ecological environment is analyzed. Finally, the authors point out the problems that need to be paid more attention to in the future researches.
