用土工加筋防治土冻胀的研究

Study on prevention of frost heave with reinforcement

作者通过室内冻结试验，研究约束应力抑制土冻胀的可能性，结果表明：要保持建筑物的冻胀位移足够小，不需要约束应力大到“中断压力”而可以通过加筋或选择适当的结构形式提供约束应力，使冻胀土体向融土区的方向压缩，从而大幅度减小建筑物发生的冻胀位移。

A series of laboratory frost tests has been performed in order to study the application of restraining pressure to prevent from frost heave of soils. Based on the experimental study the results show that, for keeping frost heave displacement small enough to prevent structures from damag, it is not necessary to apply the restraining pressure to as high as ' Suspended pressure'. The application of reinforcement or suitable design of structure can provide an restraining pressure to greatly reduce the frost-heaving displacement of the structure.
