【摘要】：陽(yáng)澄淀泖區(qū)屬于典型的平原河網(wǎng)地區(qū),河湖密布,地勢(shì)低洼。為了抵御洪水,區(qū)域內(nèi)建成大小聯(lián)圩366個(gè),約占總面積的50%。圩區(qū)建設(shè)是平原河網(wǎng)低洼地區(qū)的重要防洪排澇措施,但隨著圩區(qū)規(guī)模的擴(kuò)大、防洪排澇標(biāo)準(zhǔn)的不斷提高,使得骨干河道洪水位上升,對(duì)區(qū)域防洪產(chǎn)生重要影響。以實(shí)測(cè)資料和圩區(qū)現(xiàn)狀調(diào)查為基礎(chǔ),構(gòu)建了能反映現(xiàn)狀河網(wǎng)、圩區(qū)分布、圩區(qū)調(diào)度的數(shù)學(xué)模型,定量分析了圩區(qū)排澇對(duì)區(qū)域防洪影響。所建立的數(shù)學(xué)模型及對(duì)圩區(qū)排澇對(duì)區(qū)域防洪的影響分析可為陽(yáng)澄淀泖區(qū)的洪水計(jì)算、防洪規(guī)劃、圩區(qū)建設(shè)提供理論依據(jù)。
[Abstract]:Yangcheng Maodian area belongs to the typical plain river network area, the rivers and lakes are dense, the topography is low. In order to resist the flood, 366 large and small United fair are built in the area. The construction of polder area is an important measure of flood control and drainage in low-lying areas of plain river network. However, with the expansion of the scale of polder areas and the continuous improvement of flood control and drainage standards, the flood level of the backbone river is rising. Based on the measured data and the investigation of the current situation of the polder area, a mathematical model which can reflect the current river network, the distribution of the polder area and the operation of the polder area is established. The mathematical model established in this paper and the analysis of the influence of drainage on regional flood control can provide theoretical basis for flood calculation, flood control planning and construction in Yangcheng Maodian area.
