土工合成材料在吹填造地工程中的应用

土工合成材料作为一种新型建筑材料,在工程建设中发挥着越来越重要的作用。针对该类型材料在吹填造地工程中防渗、反滤的作用，分析材料的物理、水力性能，并结合吹填造地项目的围堰工程和围埝工程，介绍该种材料在不同施工环境下的作用和功能。结果表明，土工合成材料在吹填造地项目中能发挥很好的防渗、反滤作用，对其存在的缺点，应加以规避或进行适当防护，以便最大程度发挥其主要功能。

Application of geosynthetic in dredger filling project

As a new building material,geosynthetic plays an increasingly important role in engineering construction.Aiming at the anti-seepage and anti-filtration effects of this type of material in the land reclamation project,we analyze the physical and hydraulic characteristics of the material,and introduce the role and function of the material in different construction environment combining with the cofferdam and enclosure engineers of the dredger filling project.The results show that geosynthetic can play a very excellent role of anti-seepage and filtration in dredger filling project.The shortcomings of geosynthetic should be avoided or properly protected in order to maximize its main function.
