摘　　要：南水北调中线一期穿黄工程北岸渠道经过老蟒河,采用河道倒虹吸的方式进行交叉。由于倒虹吸进出口渐变段扶壁式挡土墙较高,高度13.1 m,挡土墙稳定是工程设计的一个难题。采用土工格栅加筋的形式,突破传统设计思路,使常规扶壁式挡土墙结构与加筋挡土墙新型结构有效结合,对今后的高挡土墙设计有一定借鉴作用。The channel on the northern bank of the first phase Yellow River-crossing project at middle route of the South-to-North Water Transfer Project passes through the Laomang River via inverted siphon. As the buttressed retaining wall at transition section of the inverted siphon＇s inlet and outlet is 13. lm high, to keep the wall stable is difficult in design. The use of reinforced geotechnical grille is a breakthrough to conventional design for the grille can effectively band conventional buttressed retaining wall and reinforced retaining wall together, which is referential for design of high retaining wall in the future.
