婺源县城区防洪治理工程设计

The urban flood control embankment engineering design of Wu-Yuan City

针对婺源县城区防洪体系中防洪堤未封闭,涝区无挡洪排涝设施,防洪堤防洪标准偏低、无法抵御20年一遇洪水等问题,结合防洪堤现状、防护对象等因素,设计采取有针对性的新建土堤、新建防洪墙和干砌石护岸等为一体的防护加固方案。计算结果表明:防护加固建筑结构整体稳定性、抗渗性和应力指标均符合规范要求,防洪加固方案具有较好的技术和经济效益。

Aimed at the problems of unblocked flood protection levee, no blocking flood drainage facilities in water-logging area and cannot resist the 20 year design flood with low flood control standard in the Wu-Yuan urban flood control system, according to the overall planning of urban flood control, the distribution of Le-An river, and flood control standard of the planning years,combining with the existing flood control facilities, protection object and other factors, the integrated protection and reinforcement scheme with building new embankment, new flood wall and dry masonry stone revetment has been design and adopted. The anti sliding and anti overturning stability, seepage stability and stress analysis results show that the overall stability, permeability and stress indicators of the protection and reinforcement structure conform to the standard requirement totally. The flood prevention and strengthening scheme has good technical and economic benefits.
