一维渗流引发介质颗粒位移维数的概念模型分析 冉兴龙 王庆良 摘 要:从Helm的三维固结问题的质量连续性方程出发,通过对一维渗流概念模型分析,定性讨论了非固结含水层的一维储水渗流过程与释水渗流过程中的颗粒位移维数问题,指出颗粒位移的减维概化必须审慎从事,原因在于目前尚缺乏相应的理论支持。这对与抽注地下水有关的地层形变及地质灾害研究具指导意义。 ANALYSIS OF CONCEPTUAL MODEL FOR DIMENSIONALITY OF MEDIA SAND DISPLACEMENT CAUSED BY ONE-DIMENSIONAL PERMEATION RAN Xing-long(Opening Research Laboratory About Water Resource and Land
Environment in Arid and Semiarid Region Under the Ministry of Land Resource, Changan University, Xian 710054, China) Abstract:Starting with Helms mass continuity equation of
three-dimensional consolidation problems, the paper qualitatively discusses the problem of
dimensionality of sand displacement in one-dimensinal permeation conceptual model
according to the cases of water storage and water release,then suggests that dimension
reduction generalization of sand displacement be carefully done because of lack of
corresponding theory supporting it up to now.The conclusion will provide some guide for
research of aquifer deformation and geological disasters caused by pumping (or
pouring)water from (or into)unconsolidated sediments. |
