Combining with the factual engineering examples,the paper adopts the hydraulic calculation and practical observation to investigate the reasons for the tube explosion and leakage of the long-distance inverted siphon gravity water-supply pipelines,and points out the effective solutions to avoid the tube explosion and leakage and to improve the flowing capacity of the pipelines,so as to direct the practice.%结合具体工程实例,采用水力计算和实践观察的方法查找长距离倒虹吸重力输水管线爆管漏水原因,并针对性地提出了既能避免爆管漏水又能提高管道过流能力的有效解决办法,以期指导实践。
