摘    要:异常温压条件下的渗透系数和弹性储水系数是评价深层地下水资源量的关键水文地质参数。本文针对目前国内外在深层地下水资源评价研究中,沿用浅层地下水的非稳定井流试验求参数所造成的弊端,考虑到深层地下水因埋藏深度很大而形成的异常温压条件,提出了通过实验室测定岩样,水样的弹性模量、泊松比、孔隙度、渗透率、液体体积压缩系数、粘滞系数等,进而计算深层地下水所处的特定环境中的水文地质参数的方法。

关 键 词:异常温度  异常压力  深层地下水  水文地质参数  计算方法

Abstract: Coefficient of permeability and storativity under unnormal conditions of temperature and pressure are the key hydrogeological parameters for resource evaluation of deep groundwater. To aim at the disadvantages of the resource evaluation of deep groundwater, which are caused by improperly using the experiment methods of shallow groundwater unsteady flow to obtain the hydrogeological parameters, and to consider the unnormal conditions of tem- perature and pressure of the deep groundwater caused by its great burying deepth, an ap- proach is presented in this paper to determine Young's modulus, Poisson's ratio, porosity, permeability, coefficient of compressbility, viscosity etc. under unnormal conditions of tem- perature and pressure by experiment, furthermore, to calculate hydrogeological paraments for the special environment of deep groundwater. Finally, the reliablity of the approach is proved through comparing the calculating result of a field example with the numerical one of the finite Element Method.
Keywords:: unnormal condition of temperature  unnormal condition of pressure  deep groundwater  hydrogeological parament  calculation method
