毛细作用下岩石吸水作为一种水分传输现象在诸多领域有极其重要的影响。推导了岩石毛细直管吸水模型，在详细讨论已有吸水试验方法的基础上提出了一种吸水量量测新方法。结论如下：①新试验方法以称量剩余水量为基础，可以实现岩石吸水过程中吸水量连续、精确的量测，且可以满足一维或三维2种边界条件；②采用试验新方法，在石膏质岩初始吸水阶段，其吸水量与时间的关系基本上满足毛管理论模型，新方法能较好地适用于岩石毛细吸水试验；③分析了吸水试验数据拟合时相关系数－频次的关系，证明了试验新方法具有较小的系统误差，试验数据更加稳定与可靠。

Capillary water absorption in porous rock,as a water transport phenomenon,is of extreme importance in many fields.The kinetics of capillary water absorption of rock was derived and discussed in detail,and then a new approach of measuring the capillary water absorption was proposed.We conclude that 1 )the new approach is based on measuring residual water,thus is simple and accurate in continuously measuring the genuine water absorption rate of rocks,and meets two-dimensional or three-dimensional boundary conditions;2)in the initial stage of water absorption of gypsum rocks,the relationship between water absorption value and time is consistent with capillary theoretical model;3)the relationship between correlation coefficient and frequency during the fitting of test data proves that the new approach has small errors and the test data is stable and reliable.
