浏河口土工合成织物加筋土护岸工程

位于长江河口段的浏河口河岸因受潮汐、风浪、船行波的侵蚀和冲刷、河岸严重坍塌，已成险工，急需修建护岸工程。工程中使用了高分子聚脂合成纤维修建加筋土挡墙，并在加筋体表面护砌混凝土预制块。由于土工合成筋材和土体界面剪向应力的效应，使其土体所受剪力转化为筋材的拉力，充分发挥了筋材强度高的特性，限制了土体的侧向变形，保证了岸线的内部稳定。使用钢筋混凝土锚定板护面，既可防止土工合成织物的老化，又可保护河岸免受

Reinforcing river bank using synthetic fibre at Liuhekou

The river bank at Liuhekou, located in the estuary of Yangtze River, has suffered serious damage due to erosion by tide, wind and ship waves,and urgently needs to construct a bank protection works. For this reason, the reinforcing synthetic fibre earth wall with precasted concrete caver was constructed. The synthetic fibres would serve the function of restricting occurrence of the earth body's lateral deformation, thus ensuring the river bank stability. The concrete cover anchored to the earth body not only protects the river bank from erosion by current,but also prevents the synthetic fibre against aging. Application of synthetic fibre to bank protection is a reform of conventional bank protection method, which would be widely used in this engineering area.
