But when we mine commensuration groundwater, the falling velocity water level and range of the deep hydrous stratum are bigger than the shallow hydrous stratum. And the quantity of subsidence is not obvious different. 2. Analyzing the relation between the stratum of groundwater and land subsidence, with the depth of aquifer bed increased, the proportion that the released water because of compressibility of strata possessed become bigger, and it cause land subsidence more serious. 3. The physical and mechanical properties and the consolidation state of stratum do not become better with the depth increased.

依据: ①一般情况下,随深度增加,地层的压缩性会渐下;但是开采同量的地下水,其水位下降的速率及幅度深部含水组比浅部含水组要大的多,两者引起的沉降量不会有明显的差别;②从地下水开采资源组成与地面沉降关系分析,含水层深度越深,其中的压密释水量所占的比例也越大,造成的地面沉降也越严重;③地层的物理力学性质及固结状态,随深度的增加,也不完全是越来越好。

In this thesis a mathematical model referring to the relationship between the case depth and carbon distribution by using a nonlinear regression. The electromagnetic characteristics in carburized materials were discussed. Results show that inductivity and magnetic inductivity depend on the carbon concentration in carburized layer. A relationship model between the electric, magnetic inductivity and carbon concentration was built.

The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it's also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数,测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢,在某一范围内,当一阶导数呈现符号转换时,相对应的深度点的测井值即为该范围内极大值;测井曲线的二阶导数则表示曲线的凹凸性,在某一范围内,当二阶导数呈现符号转换时,相对应的深度点代表了测井曲线的拐点,即反映曲线凹凸性变化的转折点,亦即地层的分界面。

Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.

环境氡主要来自岩石、土壤,而目前环境氡研究中与地质环境结合很少,为此作者以物理场为基础,运用气体运移的费克扩散定律和达西定律,建立起壤中氡浓度分布与大地—大气间氡交换理论模型,首次在理论上将环境氡与地质环境结合起来;论文中从理论上讨论了模型中各参数对空气中氡浓度的影响,发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异;通过面状氡源条件下的氡运移模型实验,研究了介质中氡的运移与分布,实验数据表明氡浓度随深度的变化规律可用指数函数描述,在放射性元素分布均匀的条件下,介质中不同深度和同一深度不同点的氡浓度随时间而变,但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的;同时研究了不同介质间氡的交换,并验证了所建立的理论模型;运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布,取得了较好的效果。
