摘　　要：叙述了利用重力、水准资料建立(似)大地水准面的过程,并把这一技术成功应用到南水北调西线工程施 测像控点高程,取得了显著的经济效益和社会效益。最后探讨了该技术在黄河流域大地水准面的可行性。The authors introduced the earth water level building condition with gravity and water level materials, which successfully applied in control point height of construction and survey of South-to-North water transfer West line project and achieved remarkable economic and social benefit. The technology feasibility applied in the Yellow river basin earth water level was probed into here, too.
