摘要
通过对周天河段的演变分析,认为目前周天河段的过渡形式虽为周公堤水道上过渡形式、天星洲水道左槽一次过渡形式,但周公堤水道过渡段已产生浅埂,同时形成交错浅滩,天星洲水道的天星洲洲体左缘冲刷后退,过渡形式存在向二次过渡演变的趋势,该河段航道条件将趋于不利。针对周天河段目前存在的问题及不利发展趋势,提出该河段的具体航道整治思路与工程措施,为周天河段的航道综合治理指明了方向。
By analyzing the evolution of Zhoutian river reach, it is thought that although the transition form of Zhoutian river reach is the upper-transition in Zhougongdi waterway and the left slot once-through transision in Tianxinzhou waterway at present, there is a shallow ridge in the transition section of Zhougongdi waterway, and the waterway forms a staggered shoal. The left margin of Tianxingzhou retreats because of it＇s erosion, and there is a trend of twice-through transition, so the waterway conditions tends to be disadvantageous. According to the present problems and adverse development trend in Zhoutian river reach, this article puts forward a specific waterway renovation ideas and plans, which points out the direction of comprehensive regulation for the waterway of Zhoutian river reach.
