针对灌区中渡槽普遍存在的病害现象，以引丹灌区某渡槽为研究对象，利用有限元软件对渡槽的实际使用状态进行分析,模拟渡槽在各种工况下的的运行状态。结合现场检测手段，分析渡槽产生病险的原因，为渡槽的使用状态做出科学的鉴定。分析结果表明考虑到渡槽防渗抗裂的要求，建议研究使用预应力混凝土渡槽。同时对碳纤维布加固混凝土渡槽的工艺要求做了简要的介绍。

For studying the general disease of aqueducts of irrigation district, some aqueduct in various conditions of operation was simulated by using the finite element method with an example of the Danjiangkou Irrigation District. With the means of field detection, the reasons for the aqueduct diseases were analyzed and the risk for the practical state to use the aqueduct was scientifically identified. The results show that for satisfying the requirements of anti seepage and anti cracking, the use of prestressed concrete aqueduct is reasonable, safe. At the mean time, the process demands of CFRP (carbon fibre reinforced plastic) reinforced concrete aqueduct are briefly introduced.
