摘要
拟建的名山桥位于缙云好溪河流,根据模型验证的需要经及现有的好溪水文资料,利用二维河流数学模型和经验公式对桥墩局部冲刷进行了对比计算和分析,对桥梁墩台防护的措施及其降低水流流速,干扰水流的紊动,减少马蹄形旋涡强度,降低水流的冲刷能力的水动力特性进行了分析.为工程设计和管理提供了依据.
The proposed Mingshan Bridge is located in Haoxi River, Jinyun. According to the needs of model validation and hydraulic data, two dimensional mathematical model and empirical formula are used to calculate and analyse the partial scour of the bridge pier. And the protective measures are suggested and the hydrodynamic characteristic is discussed in order to reduce flow velocity, to decrease turbulence flow interference, to weak horseshoe vortex strength, to lessen water ero- sio, which offers basis for engineering design and management.
