    Abstract: Numerical simulations and laboratory tests on soil samples with compaction degrees of 94%, 96%, and 98% are carried out to study the laws of capillary water rising and control techniques. The silty soil samples are obtained from the Yellow River–flooded area of eastern Henan. The relation formulas between capillary water rising height and time are obtained through fitting. Results show that (1) the rising height gradually stabilized with the passage of time, reached about 130 cm on the 10th day, and eventually arrived at a maximum height of 285 cm; (2) the rising speed of capillary water was inversely proportional to the degree of compaction, especially when reaching the minimum rising height and speed with a compaction degree of 98%; and (3) the graded crushed stone, cement stabilized soil, and fiber cement stabilized soil effectively eliminated the rising of capillary water. Thus, properly increasing the compaction degree of the subgrade and adding a blocking layer of capillary water prevent the capillary water from rising, which improves the water stability of the subgrade.
