摘　　要：针对南水北调中线工程主干渠的水力要素确定了吴庄隧洞的总过水断面面积,对三种常见的断面形式:分离双洞、双连拱隧洞和三连拱隧洞,进行了优缺点比较,最后确定采用分离双洞形式。依据工程类比,对分离双洞方案进行了支护参数设计,并对二次衬砌进行了截面强度和抗裂要求检算,方案合理。The total flow cross area of Wuzhuang Hydraulic Tunnel is determined according to the hydraulic factors of the main channel of the Middle Route Works for the South - North Water Transfer Project. After the advantages and disadvantages of three common schemes, namely double - separate - tunnel, double - spantunnel and triple-span -tunnel, are compared with one another, the double - separate - tunnel is selected as the final scheme. Based on the engineering analogy method, the supporting parameters are designed for this selected scheme. The results of strength and anti-crack calculations for the lining show that the separate - double -tunnel scheme is reasonable.
