| 摘 要： | 舟曲“8．8”特大泥石流灾后治理中的关键技术研究是治理工程首先需要解决的问题，包括3个关系，即泥石流流量与排导沟断面关系、泥石流冲击力与拦挡坝强度关系、泥石流物源级配与柔性防护拦疏关系。提出了长流水小排水槽、一般山洪泥石流中排导槽、特大山洪泥石流生态景观休闲大缓冲区的设计理念，解决了百年一遇泥石流对排导沟流量与断面的设计要求。提出用钢混结构重力式拦挡墙替代原有浆砌块石重力式拦挡墙，满足了坝体对冲击力与强度的关系。建议在流通区设置SNS柔性防护网，采用钢丝绳环形网在发挥拦挡的同时达到泄水的要求。研究成果对于舟曲泥石流灾后治理设计方案具有科学价值。

| Abstract: | The first problem to be solved in control engineering of debris flow included three relationships,namely,the relationship between the discharge of debris flow and cross section of the drainage channel,the impact force of debris flow and the strength of the dam,the material source graduation of the debris flow and the flexible protection.It is the key technology of debris flow controlling after the 8.8 extra large-scale debris flow in Zhouqu.It is proposed that long water with small drainage channel,general ... |
