【摘要】 特大地震诱发了大量滑坡、崩塌、泥石流、堰塞湖和不稳定斜坡等次生地质灾害,水土流失非常严重,造成震区江河严重破坏。地震灾区河道修复是灾后恢复重建主要任务之一。四川大学水力学与山区河流开发保护国家重点实验室经过对震区的现场考察、结合灾区河道修复工程开展了相关的水沙动力学物理模型、数学模型与历史模型相结合的复合模型研究,取得了阶段性成果。作者结合国内外有关河道修复问题的研究进展,综述了河流修复在汶川地震灾后重建的重要性、河道修复的一般原则与地震灾后河道修复特殊原则、地震灾区河道修复的稳定性问题、地震灾后河流修复研究方法与案例。通过总结两年来抢险救灾与灾后重建的河流修复科学研究与工程实践,提出了灾后河道修复继续完善的建议。更多还原

【Abstract】 After the Wenchuan earthquake occurred in 2008,rivers in the earthquake district have been damaged seriously by Landslides,debris flows and barrier lakes.Intensive researches have been conducted during the disaster relief,recovery and reconstruction.Based on the selective literature review of mechanism and technology studies of stream corridor restoration,the general principles and special principles in stream corridor restoration techniques to secondary disasters of earthquakes,the stability of rivers in the earthquake district,and the methodology and practice examples were summarized.It was suggested that further studies are especially required,including strengthen inter-disciplines studies in areas of hydraulic engineering,geo-science,and ecologic and environmental science to explore theory and key techniques of river corridor restoration after the Wenchuan earthquake.更多还原
