【摘要】：本文采用橫向比較和縱向比較的方法,通過模擬室內(nèi)垂直入滲試驗,以純鋁渣為參照,分析3種容重(1.1 g/cm3,1.3 g/cm3,1.4 g/cm3),5種質(zhì)量比例(1：10,1：5,1：3.3,1：2.5,1：2)摻土鋁渣的入滲特性,討論入滲速率,累積入滲量,濕潤鋒與時間的關(guān)系,運用spss19.0從三方面(考斯加可夫經(jīng)驗公式、通用經(jīng)驗公式、冪函數(shù))對實測數(shù)據(jù)進行回歸分析。主要結(jié)論： (1)摻土鋁渣的入滲速率與容重呈負相關(guān),在平均入滲速率方面,容重為1.1g/cm3,質(zhì)量比例為1：2的最大,容重為1.4g/cm3的純鋁渣的最小。容重為1：1的純鋁渣達到穩(wěn)定入滲的時間最短。最大穩(wěn)定入滲時間是最小穩(wěn)定入滲時間的2倍。(2)兩種模型均有較高的擬合度,只在初始入滲階段和穩(wěn)定入滲階段有所偏差。但總體而言通用經(jīng)驗公式比考斯加可夫經(jīng)驗公式有較好的擬合度。 (3)同一容重條件下,質(zhì)量比例為1：2的累計入滲量最大,其次是純鋁渣,質(zhì)量比例為1：3.3的累計入滲量最小。所以摻入一定比例土可以有效減小其入滲強度。3種容重的曲線均有2個轉(zhuǎn)折點。與容重為1.1g/cm3的累積入滲量曲線相比,容重為1.3g/cm3和1.4g/cm3的相對平緩且接近一致。 (4)在入滲過程的任意時刻,都存在濕潤鋒距離1.1 g/cm31.3 g/cm3 1.4g/cm3;質(zhì)量比為1：10,容重為1.1g/cm3的濕潤鋒隨時間的變化最大。 (5)容重為1.1g/cm3的濕潤鋒推進過程之間差別不大,而容重為1.3g/cm3和1.4g/cm3的濕潤鋒推進過程間差別較大。 (6)對濕潤鋒運行距離的實測數(shù)據(jù)進行線性回歸分析后發(fā)現(xiàn),R2大于0.950,擬合度較高。
[Abstract]:In this paper, by means of horizontal and longitudinal comparison, by simulating the indoor vertical infiltration test and taking pure aluminum slag as reference, the infiltration characteristics of three kinds of aluminum slag doped with aluminum slag (1.1 g / cm _ 3, 1.3 g / cm _ 3, 1.4 g / cm ~ (3)) are analyzed, and the infiltration characteristics of aluminum slag doped with soil are discussed, and the infiltration rate, cumulative infiltration rate, and cumulative infiltration are discussed. The relationship between wetting front and time is analyzed by spss19.0 regression analysis of measured data from three aspects (Koschakov's empirical formula, general empirical formula and power function). The main conclusions are as follows: (1) the infiltration rate of soil-doped aluminum slag is negatively correlated with bulk density. In terms of the average infiltration rate, the bulk density is 1.1 g / cm ~ 3 and the mass ratio is 1: 2. The minimum of pure aluminum slag with bulk density of 1.4 g / cm3. The time of stable infiltration of pure aluminum slag with bulk density of 1: 1 is the shortest. The maximum stable infiltration time is 2 times of the minimum stable infiltration time. Only in the initial infiltration stage and the stable infiltration stage there is a deviation. But in general, the general empirical formula has a better fitting degree than the Koschakov empirical formula. Under the same bulk weight condition, the accumulative infiltration amount of 1: 2 mass ratio is the largest. Secondly, pure aluminum slag, with a mass ratio of 1: 3.3, has the smallest cumulative infiltration. Therefore, the curves of volume density of 3 species that can effectively reduce the infiltration intensity have two turning points, compared with the cumulative infiltration volume curve of 1.1 g / cm ~ 3 of bulk density. The bulk density of 1.3 g / cm3 and 1.4 g / cm3 is relatively flat and close to the same. The wetting front distance of 1.1 g / cm31.3 g / cm 3 1.4 g / cm 3; the wetting front with a mass ratio of 1: 10 and bulk density of 1.1 g / cm 3 changed most with time. However, there is a great difference in the propulsive process of wetting front with bulk density of 1.3 g / cm3 and 1.4 g / cm3. (6) the linear regression analysis of the measured data of the running distance of wetting front shows that R2 is greater than 0.950 and the fitting degree is higher.
