摘　　要：万家寨引黄一期工程南干隧洞总长达100km,洞段的防渗设计尤为重要。由于采用了全断面双护盾掘进机(TBM)施工,因而管片衬砌结构自身特点决定了其接缝防渗构造的特殊性。隧洞的防渗设计包括管片衬砌防渗止水系统和接缝止水密封垫两部分。The total length of the tunnel of the first-stage construction of the Southern Main Line of Wanjiazhai YRDP is 100 km, the design of the seepage prevention of the tunnel section is very important. Because the TBM is adopted in the construction, the features of the duct piece liner structure determine the particularities of the joints＇ seepage prevention structure. The design of the seepage prevention of the tunnel includes two parts of the duct piece liner seepage prevention and watertight system and the joint watertight sealing plate.
