水平冻结加固冻胀融沉模拟试验

Simulative Experiment of Technique for the Prevention and Cure of Frost Heave in a Soil Frozen Stabilization

为填补当今学界在冻胀防治技术的应用研究方面的空白,文章结合上海地铁建设工程实际,采用模拟试验的方法,分析研究了预留管拔除法和热盐水循环法抑制冻胀的机理以及抑制冻胀的实际效果和相关的影响因素,为上海软土冻结加固冻胀融沉的防治提供了理论依据和有关的参考数据.

In the light of the practice of Shanghai subway project,using the simulative experiment,this article describes the correlative theories,results of application and the correlative influence with the methods by means of drawing the pipes installed ahead and cycling the hot saltwater.And it also provides the theoretical gist and correlative data for the prevention and cure of frost heave in a soil frozen stabilization in Shanghai.
