由于泥石流动力过程的复杂性和理论研究的不完善,拦砂坝防治工程中关键参数计算与拦砂坝结构设计仍然存在诸多不足。首先,简要介绍了拦砂坝工程防治的发展历程及其重要作用。然后,从溢流口过流能力计算、坝体所受泥石流冲击力、坝后冲刷深度与基础埋深以及坝体结构稳定性4个方面详细评述了非透过性泥石流拦砂坝研究取得的主要成果及存在的问题。最后,从设计参数计算方法、新型拦砂坝结构、新型抗冲耐磨材料的研发与应用以及拦砂坝防治体系建设等方面探讨了非透过性泥石流拦砂坝研究的发展趋势。
Due to the complexity of the debris flow process and the imperfect theoretical research, there are still many shortcomings in the calculation of key parameters and structural design of the dam. First of all, it briefly introduces the development history and important role of sand bar engineering. Then, based on the calculation of the over flow capacity of overflow, the impact force of debris flow, the depth of scour after dam, the depth of foundation and the structural stability of dam body, the research results of impervious debris flow dam The main achievements and problems. Finally, the development trend of research on impervious debris flow barrage is discussed from the aspects of design parameter calculation method, structure of new type of barrage, development and application of new type of anti-abrasion material and construction of prevention and control system of it.
