弱渗透松散和坚硬岩石的渗透性测定方法

固体有害废物安全填埋场基础弱渗透岩石的渗透性，大多数情况下都由实验室和野外方法测定．测定方法的适用性取决于岩石种类、岩体状态和渗透性数量级别．在同一实验段内采用不同的实验方法，一情况下导致产生两个数量级的误差，而更大的不可靠性与使用不同的评价方法有关．因为可靠并可引用的渗透性测定值在废物安全填埋场建设中对地质屏障的评价具有重大意义，如果各地能同时列出科研规划，共同研究对所有可能存在的地质屏障岩石进行全面分析评价，确定不同实验方法之间相关关系，以及使评价方法尽可能统一，是十分必要的

Permeability of Low-Permeable Soils and Rocks

A variety of laboratory and field testing methods is available for the assessment of Low-permeable soils and rocks. Their application depends on the type of rock, the properties of the rock-mass and the expected range of permeability, Different test methods applied in identical test sections do not produce reduplicable results but vary within two magnitudes of power ten.Further aberrations are bound to different evaluation methods. in order to guarantee for reliable and reduplicable results for the assessment of geological barriers of Landfills a coordinated research project is consider necessary. This should cover all potential types of buffer rocks,provide for correlation between the different test techniques and standardize the evaluation methods.
