毛细上升

It is similar to the force that causes a liquid to rise in a capillary tube - the capillary attraction, or capillarity.

这是内聚力作用于液体表面的结果；正如引起液体沿毛细管上升的毛细引力。

In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.

论文以厦门至成都高速公路湖南郴州段的红粘土为研究对象，以环境因素作用下红粘土路基的变形特征与防护方法为研究目的，通过室内试验研究了不同压实度红粘土的持水性能、毛细上升、湿热耦合迁移及湿化变形等特征，借助郴州地区连续两年的气象数据，模拟在地下水和大气的共同作用下路基内部红粘土水分迁移与路基变形的耦合过程，主要研究内容及结论如下：(1)针对不同压实度的红粘土，系统开展了其渗透、固结、收缩、剪切等试验研究。
