摘　　要：南水北调中线穿黄工程北岸竖井修建在高地下水位、透水的黄河漫滩砂层中,竖井深度超过70 m,通过对其超深防渗灰浆墙、超深地下连续墙及满堂内衬等施工关键技术的研究,对丰富和完善超深竖井和防渗工程的施工理论、技术具有重要意义。详细介绍了该工程中涉及到的超深灰浆墙、超深地下连续墙、帷幕灌浆等的施工方法及施工要点。竖井施工质量达到了盾构始发及掘进施工要求。其中超深竖井与防渗工程施工技术可供类似工程参考。With a depth of over 70m,the shaft on north bank of the Yellow River Crossing Project of the Middle Route Project of South-to-North Water Diversion（MRP-SNWD） is built in sand layer of river floodplain where is characterized by high groundwater levels and permeability.Through studying the key construction technologies such as super-deep impervious mortar wall,super-deep diaphragm wall and full-space lining,we can obtain significant experiences of super-deep shaft and anti-seepage engineering.We present in detail about the construction method and key points of super-deep mortar wall,super-deep diaphragm wall and curtain grouting.The construction quality can meet demands of starting and driving of shield machine.
