土工管袋理论分析与设计计算

Theoretical analyses and design methods of geosynthetic tubes

土工管袋技术具有制作简单、施工及运输快捷、经济环保等优点,近年来被广泛用于防洪防汛及水位控制、防波堤、海岸防侵蚀、堤坝、污水存贮和污水沉积等工程领域,根据制作材料和施工工艺的不同可将土工管袋分为土工膜管袋、土工织物管袋和橡胶坝三种.本文综合介绍了土工膜管袋、土工膜垫、土工织物管袋、支挡土工膜管袋以及橡胶坝等结构形式的土工管袋理论计算方法和相应的简化设计计算公式和图表,以期对类似的工程建设和设计起到一定的参考意义.

Geosynthetic tubes are beneficial because they allow easy manufacturing,construction as well as transportation,and they are environmentally friendly.Therefore,they have been widely employed in flood control and water retention,breakwater,coastal protection,dike construction,and waste sludge dewatering in several countries.Based on the differences between manufacturing materials and construction procedures,geosynthetic tubes can be categorized as follows:Geomembrane tubes,geosynthetic tubes,and rubber dams.This study reviews the basic theory and design methods for geomembrane tubes and mats,geotextile tubes,wedged geomembrane tubes,and rubber dams to provide a basic understanding of geosynthetic tubes designs.
