摘要
呼兰河口航道裁弯取直工程和河口大桥工程位于呼兰河下游,距离河口位置约7km处。为研究桥址河段在航道实施裁弯取直工程后的河道河势变化,预测工程实施对呼兰河航道航运和对桥梁安全的影响,建立了呼兰河河口段二维数学模型,从工程实施前后水位和流速变化的结果,分析了工程实施后对航运条件、呼口桥桥墩、工程段河势的影响。
The curving cut-off project at Hulan River estuary and the project of estuary bridge are located in the down- stream of Hulan River, about 7km from the estuary. In order to study the changes in river regime after the project in the bridge area, and to predict the influence to waterway shipping and the bridge safety, a 2-d numerical model of Hulan River estuary was built. From the simulated resuhs of water level and velocity change between before and after the pro- ject, the project influence to shipping conditions, bridge pier, fiver regime were analyzed.
