Comprehensive tests on rising height of capillary water

More Information
  • Published Date: October 14, 2008
  • According to the comprehensive tests on the rising height of capillary water for twelve kinds of different coarse grained soil and fine grained soil by use of the method of standpipe,the relationship between the rising height of capillary water and time was obtained,and the influencing factors and rules were analyzed.The relationship between the rising height of capillary water of coarse grained soil and time could be drawn by the double-unit regression equation in the logarithmic coordinate.The parameters were related with composition of grain and degree of compaction.The data of the steady rising height of capillary water were obtained,and the regression equation of coarse grained soil on steady height and physical indexes(effective grain d10 and porosity n) was found.Compared with Hazen’s and other expressions that could estimate the steady height of capillary water of coarse grained soil,the proposed method was satisfactory,and the defects of the latter were pointed out.
