The researches indicated : ( 1 ) the seepage flow field of infiltration diversion is characterized by three - dimensional, saturated and steady flow. there is the close hydraulic relationship between the river and the groundwater in the filtering bed, and the groundwater is confined
研究表明: ( 1 )滲濾取水的滲流場具有典型的飽和三維穩定流特徵;滲濾取水濾床中地下水與河流的水力聯系比較緊密,濾床中的地下水處于承壓狀態。( 4 ) the maximum water quantity becomes greater, the better is the filtering bed permeability, the higher the river hydraulic conductance, the higher the river level, the larger the water - collecting area and the bigger the distance between collecting pipes. the water quantity varies directly with drawdown
( 4 )濾床的滲透性能越好,河床水力傳導系數越高,河水水位越高,取水面積越大,取水管之間的間距越大,則最大取水量越大;水位降深與取水量成正比關系。Visual modflow computer code was selected to simulate heads distribution, calculate the zone budgets of the area, evaluate the effect of external stresses on the groundwater head, to determine how much water would be diverted from the river as the result of pumping and to demonstrate how the groundwater model can be used as a comparative technique to formulate a new approach for the quantitative groundwater vulnerability assessment in order to optimize utilization of the resource
在分析河床沉積物滲透性對模型結果的影響時,採用了實際野外水文地質條件而不像前人所採用的假想模型。本論文用visualmodflow建立數值模型模擬預測了地下水水頭分佈,計算區域的水均衡,分析源匯項對地下水水位的影響。在此基礎上進行了全區的地下水脆弱性評價,為地下水資源的合理開發利用提供依據。In this project, the maximum height of the dam is 81m, but the deep overburden in the riverbed has the depth of 147. 95m which is about two times of the maximum height of the dam body, so the seepage and liquefaction prevention of the dam foundation becomes the key and important problem in the design of the dam project. the static stress and deformation under three different projects - horizontal blanket project, clay core project and asphalt core project - for the dam is analyzed comprehensively. the damage that may be induced by variable factors on the dam body in time of engineering completion and water impounding operation period is seriously studied
其次,將這一模型用於分析下坂地水利樞紐工程,由於該工程河床覆蓋層深度最深達147 . 95m ,是壩體高度的近兩倍左右,壩基的滲流和液化成為壩體安全主要問題,本文對該壩的三種設計方案即水平鋪層防滲方案、粘土心墻防滲方案及瀝青心墻防滲方案的靜態應力位移及壩體在竣工期、蓄水期等各個階段可能產生的破壞進行了認真研究。The technique of infiltration diversion near the river, collecting the water from the riverbed, is a new one developed in recent years
集取河床滲透水的滲濾取水技術是最近幾年才發展起來的一項傍河取水新技術。Changing of the riverbed conductance provides high change in river gaining rate compared to change in river losing rate. this difference can be attributed to aquifer anisotropy, river penetration, hydraulic balance between groundwater head and river stage
其中河床沉積物滲透性的改變引發的河流得水率變化明顯大於河流失水率的變化,分析其原因為含水層的各向異性、河流的滲漏、河水與地下水的水力均衡。Generally this research successfully formulated a new approach of quantitative gva, confirmed that visual modflow can be used successfully as a comparative technique for quantitative groundwater vulnerability and evaluated the effect of riverbed conductance on river leakage
此次研究創造性地採用了一種新的地下水脆弱性定量評價方法,結果同時也說明可視化modflow可以用做地下水脆弱性定量評價和河床沉積物滲透性影響的對比技術。The river package of visual modflow code was used to understand the interaction between songhuajiang river and the nearby aquifer and the effect of riverbed conductance on river leakage. induced infiltration, reduced baseflow, river losing and river gaining are the main factors used to demonstrate these phenomena
用modflow的河流程序包對松花江與附近含水層以及河床沉積物滲透性的互聯系進行分析,並用誘發入滲、基流減少、河流失水和河流得水等4個主要因子來證明。分享友人
