摘　　要：为了提高苏通大桥主塔墩基础的安全性、确保大桥顺利施工以及大桥建成后的安全运营,实施了桥墩冲刷防护工程.利用GIS技术,确定该项工程中防护材料的抛投提前量、计算防护材料成型的工程量、分析防护区内水下地形不同时段的冲淤变化以及剖面形态等.结果表明,利用GIS技术可以精确而直观地反映防护材料的成型位置与抛投位置的关系,计算出相应的参数,为指导该项工程的顺利实施及以后的工程维护提供了科学依据,同时也为今后的类似工程项目提供了较好的借鉴和指导作用.The foundation of the main pylon pier scouring protection project of the Sutong Bridge is an important project in China. In order to ensure the safety and the successful coustructionof the foundation, GIS technology is used for confirming a throw advance distance of the protection materials, calculating the earthwork quantity of the stuff, analysing erosion and deposition change of the protection area in different periods of time, and for profile analysis. It is demonstrated that the relation between protection materials＇ molding location and paraboloid location can be reflected and calculated accurately by GIS technology. This paper provides a scientific basis for similar projects in the future.
