【 摘 要 】

Adsorptive bound water can reflect the physical properties of soil and affect its mechanical behaviour. Based on the important function of adsorbed water, the change of adsorbed water under three types of load is studied. The undisturbed samples nearby subway in Hangzhou is selected as criterion. Via the volumetric flask method, the content of the adsorbed water and the specific surface area are measured. Compared with the results of undisturbed specimen, this paper evaluated the effect of the impact, vibration and remolded and vibration. The results show that after loading the adsorption water content decreases. Among three types of load, the remolded vibration made the most significant change.
