半地上河道背景下的小城镇防洪排涝规划浅析

Brief Analysis on Flood Control and Waterlogging Drainage Planning of Small Towns under Background of Semi-terrestrial River

摘要:

防洪排涝规划是一个庞大的系统工程，为更好地指导后续的工程建设，以淄博市北郊镇孝妇河为例，根据孝妇河河底高程低于两岸地块，洪水位已高于两岸地块，已形成“半地上河”的现状情况，规划着重在源头削减、过程控制、末端存蓄三个方面构建防洪排涝体系，通过提高防洪标准、重构排涝网络、推行雨洪利用、完善管理设施等具体措施，解决北郊镇辖区内孝妇河现状“半地上河”情况给城市带来的诸多防洪排涝难题，为我国北方特别是黄河流域范围内相似河道和城市防涝规划提供参考。

Abstract:

Flood control and waterlogging drainage planning is a huge systematic project. In order to better guide the follow-up engineering construction, taking Xiaofu River in Beijiao Town of Zibo City as an example, based on the elevation at the bottom of Xiaofu River lower than the lands on both banks, the flood level has been higher than the lands on both banks, which has formed the current situation of "semi-terrestrial river". It is planned to focus on the construction of flood control and waterlogging drainage system in three aspects of source reduction, process control and end storage. By the specific measures of improving the flood control standard, reconstructing the waterlogging drainage network, carrying out the rainwater and flood utilization, and perfecting the management facilities, many problems of flood control and waterlogging drainage caused by the current situation of "semi-terrestrial river" of Xiaofu River in the area of Beijiao Town are solved, which provide the for the similar river and urban flood control planning in North China, especially in the Yellow River Basin.
