摘要
针对压汞法测得粘土类材料的孔隙总量换算成孔隙比e'后与常规方法测得的孔隙比e之间常存在很大差异,分析了造成这种差异的原因,并根据不同孔结构特征推导了多孔材料的孔隙量测试结果的修正公式。实例计算分析结果表明,修正后的结果较原结果更合理。
The void ratio e´ calculated on the basis of pore distribution test differs significantly from e determined by the conventional method. The reason of the difference was researched, and for obtaining better pore distribution characteristics and void ratio e´ a modified method based on pore structure characters was recommended, the example calculation results show that the modified method is better than the initial.
