The reason of controlling frost heave is that moisture transfer is confined due to cements. The prime theory is that penetrability of cement-improved soils falls resulting in limiting moisture transfer, which can prevent absorbing necessary water when frost heave happens.
结合土工实验数据,实验发现水泥的加入使得未冻土的透水性降低,有效限制水分迁移,阻止冻胀时吸收必需的水分,降低了析冰作用,从而有效地控制冻胀的发生。
