卵石波运移对航运影响试验研究

利用川江风和尚至长寿港典型河段动床模型.进行卵石波的形成、几何尺度及运动速度试验研究.建立卵石波要素与水力泥沙因子关系式;选择典型水沙条件水文年进行概化试验,描述卵石波的运移对浅滩航道突发性碍航的影响,分析造成浅滩突发性碍航的影响因素.并提出了浅滩突发性碍航预报及相应的整治措施.

A Test Study on Effect of Gravelwave Movement on Waterway Transport

In this paper, formation, heights, lengths and moving velocities of the gravelwave are studied on the movable bed model of the reach from Fengheshang to Changsho Port of Chuanjiang River. The formulae for the gravelwave factors are set forth. The Effect of gravelwave movement on shallow waterways are analyzed by model tests of hydrologic year under the typical conditions of water and sediment, and finally the measures for predicting sudden ocurred dangerous sections of navigable river and the appropriate regulation principles are presented.
