摘要
采用定床和动床水流泥沙整体物理模型研究了飞云江河口区水中塔基建造对所在河段的水动力和河床冲淤的变化,分析了塔基建造对河道防洪排涝、航道安全、飞云江三桥、北岸深槽的影响,对一定距离外的桥梁、航道和堤塘的不利影响较小,但塔基附近会产生4.00m左右的局部冲刷。
With integral physical model testing of immovable ＆ movable bed about current and sediment, this paper studies hydrodynamic and scouring - silting variations of the river section where the column foot is built, and analyses the impact of the column foot on flood control ＆ drainage, waterway security, Third Bridge of Feiyun River and north deep channel. Results show that adverse impact is minor on bridge, waterway and seawalls at a certain distance from the column foot, except 4-meter local scouring near the column foot.
