【摘要】 进行了软岩类材料——水泥砂浆的冻融水热迁移实验,对两种不同类型的软岩类材料进行了开放系统下具有温度梯度的水热迁移实验研究。实验结果表明:不同类型的软岩类材料水热迁移程度不同,试样中的石英矿物含量越高,温度场重新分布时间越长;温度梯度是水分迁移的主要驱动力,当温度梯度越大时,水分场则越快达到重新分布状态;孔隙率越高,则冻结过程越长。更多还原

【Abstract】 The soft rock material-concrete mortar is used during the moisture and heat transfer experiment. The two different kinds of soft rock material are experimented in the open system with temperature grads,and the result is proved:the degree of the moisture and heat transfer is different between the different soft rock materials,the content of quartz mineral in the sample is higher,the redistributing time of the temperature field is longer;the gradient of temperature is the main driving power of the moisture transfer,the grads is higher and the moisture field redistributes quicker;the porosity ratio is higher and the process of freezing is longer.更多还原
