摘要

在许多情况下,地下水流的流速很高,会产生很大的渗流力。例如,高导裂缝和隧道周围的水流。我们为弹性介质中的隧道提出了一种新的分析元素。我们将地下水流分析元素法与线性弹性分析元素法相结合,并将渗流力作为体力纳入线性弹性模型中。我们用解析元素来表示隧道和裂缝。所考虑情况的解决方案仅限于稳态流动和流固耦合。我们举例说明了隧道和断裂周围的渗流力计算结果,并与另一个数值模型进行了比较。

An Analytic Element Model for Seepage Forces in Fractured Media

An Analytic Element Model for Seepage Forces in Fractured Media

There are many situations where groundwater flow has high flow rates, causing large seepage forces. Examples are flows around highly conductive fractures and tunnels. We present a new analytic element for a tunnel in an elastic medium. We combined the analytic element method for groundwater flow with that for linear elasticity, and include the seepage force as a body force in the linearly elastic model. We represent tunnels and fractures as analytic elements. The solution for the case considered is limited to steady state flow and fluid-to-solid coupling. We present examples of the computed seepage forces around a tunnel and a fracture as well as a comparison with another numerical model.

期刊介绍: The Journal of Elasticity was founded in 1971 by Marvin Stippes (1922-1979), with its main purpose being to report original and significant discoveries in elasticity. The Journal has broadened in scope over the years to include original contributions in the physical and mathematical science of solids. The areas of rational mechanics, mechanics of materials, including theories of soft materials, biomechanics, and engineering sciences that contribute to fundamental advancements in understanding and predicting the complex behavior of solids are particularly welcomed. The role of elasticity in all such behavior is well recognized and reporting significant discoveries in elasticity remains important to the Journal, as is its relation to thermal and mass transport, electromagnetism, and chemical reactions. Fundamental research that applies the concepts of physics and elements of applied mathematical science is of particular interest. Original research contributions will appear as either full research papers or research notes. Well-documented historical essays and reviews also are welcomed. Materials that will prove effective in teaching will appear as classroom notes. Computational and/or experimental investigations that emphasize relationships to the modeling of the novel physical behavior of solids at all scales are of interest. Guidance principles for content are to be found in the current interests of the Editorial Board.
