摘要

为了研究环境相对湿度变化对土遗址浅表层水分吸附与解吸的影响规律，采用饱和盐溶液法，开展7种不同环境相对湿度条件下的4种不同干密度遗址土的等温吸放湿试验。试验结果表明：随相对湿度的增大，吸放湿速率越来越慢，达到平衡状态所需的时间越来越长；遗址土等温吸湿和放湿平衡含水率随相对湿度的增大而增大，吸湿平衡含水率随着干密度的增大而减小，放湿平衡含水率随着干密度的增大而增大；存在明显的迟滞效应，遗址土等温吸湿和放湿曲线均表现出明显的快速吸放湿和缓慢吸放湿的两阶段性。对比发现，Peleg公式和冯驰公式可以用来拟合遗址土等温吸放湿曲线，平行双指数（PEK）模型可以较好地描述遗址土等温吸放湿过程，可以利用平衡时间的前50%数据来预测最终达到平衡的时间和最终的平衡含水率。

Abstract

To investigate the influence of environmental relative humidity variations on water adsorption and desorption in the shallow surface layer of earthen sites，isothermal moisture adsorption-desorption tests were carried out on earthen site soils with four distinct dry densities under seven levels of relative humidity by using the saturated salt solution method. The test results demonstrate that with the increase in relative humidity，the rates of moisture adsorption and desorption gradually decrease，while the time required to reach equilibrium state progressively increases. The equilibrium moisture contents of isothermal adsorption and desorption of earthen site soils both rise with increasing relative humidity. Specifically，the adsorption equilibrium moisture content decreases with increasing dry density，whereas the desorption equilibrium moisture content increases with increasing dry density，showing a pronounced hysteresis effect. The isothermal adsorption and desorption curves of earthen site soils both exhibit an obvious two-stage behavior，consisting of a rapid stage and a slow stage of moisture transfer. Through comparative analysis，it is found that the Peleg model and Fengchi model are suitable for fitting the isothermal moisture adsorption-desorption curves of earthen site soils. In addition，the Parallel Exponential Kinetics (PEK) model can well characterize the isothermal moisture adsorption-desorption process，and the first 50% of the equilibrium time data can be used to accurately predict both the time to reach final equilibrium and the final equilibrium moisture content.
