胥溪乾潭镇段堤防生态建设方案研究

Research on Scheme of Embankment Ecological Construction of Xuxi River in Qiantan Town

为丰富富春江胥溪乾潭镇段旅游内涵,需对乾潭旅游码头进行扩建,将子胥公园湖泊纳入其建设范围,从而涉及该湖泊与胥溪之间的堤防调整。为不影响胥溪的行洪安全,又能使乾潭镇区达到防洪排涝标准,同时能满足码头对泊位和水域宽度的要求,对该段堤防拟定了五个生态建设方案,利用水利模型对各方案进行计算、比较,优选出最佳方案为子胥公园湖泊保留面积50%,并设置9m3/s的排涝泵站。

For enriching Fuchunjiang tourism,it is necessary to extend Qiantan tourism wharf.So it brings Zixu park lake into line with the scope of construction,which involves embankment adjustment between the lake and Xuxi river.In order to avoid affecting the floodway safety of Xuxi river and make Qiantan town reaching the criterion of flood protection and water log control as well as meeting the requirements of wharf on berth and water area width,this paper proposes five kinds of embankment ecological construction schemes.And then,water conservancy model is used to analyze these schemes.After comparing the calculated results,we recommend that retaining 50% areas of Zixu park lake and setting a drainage pump station with discharge of 9 m3/s is the best scheme.
