【摘要】 基岩裂隙水是我国分布最为广泛的地下水类型之一。本文阐述了基岩裂隙水的特点：含水层产状不规则、其赋存空间介质不均匀、同一含水层埋深不同、地下水运动状态复杂等。这些特殊的地质、地球物理特征，给常用的物探找水方法带来许多困难。本文通过对直接找水的新方法一核磁共振（ＮｕｃｌｅａｒＭａｇｎｅｔｉｃ　Ｒｅｓｏｎａｎｃｅ，缩写为ＮＭＲ）测深与间接找水的电阻率测深的对比分析，论述了ＮＭＲ测深直接找水的实质。并以实例说明了ＮＭＲ测深在探查基岩裂隙水中的应用效果。更多还原

【Abstract】 Bedrock fissure water is one the groundwater types,distributed widely in China.In this paper such features of bedrock fissure water as abnormarity of aquifers in occurrence,nonhomgeneity of space environment in Which they occurred,difference of the same aquifer in occurrence depths,and complexity of groundwater motion conditions are described.These special geological and giopysical features bring difficulties to conventional geopysical methods of detecting groundwater.By contrast of the new NMR directly detecting water method with resistivity method of indirectly detecting,water the nature of NMR detecting water method is elucidated,and effect resulted from using NMR sounding to detect bedrock fissure water shown with some examples.更多还原
