土工合成材料（目前主要包括土工织物、立工膜、聚苯乙烯硬质泪沫板）是岂立工程弄出现的一种新型建筑材料，近十多年来，在水利工程建设中的应用发展较快，对提高水利工程质量和保证工程安全起到了重要作用，同的取得了较为明显的技术经济较益。从近几年的质量监督和检查过程 Geosynthetics (currently mainly composed of geotextile, upright film, polystyrene rigid tear board) is a new type of building material that has emerged from the project. In the recent ten years, the application and development of water conservancy projects Faster, to improve the quality of water conservancy projects and ensure the safety of the project has played an important role, with the more obvious technical and economic benefits. From the recent years of quality supervision and inspection process
