| Abstract: | The artificial ground freezing is a technology to reinforce the soft soil with the theory of artificial freezing. In this paper the main technology and the basic theory of artificial ground freezing are introduced, and the main fields of its application are listed. The temperature field which affects the strength and the stability of soil reinforced by the artificial ground freezing is researched. The experiments which test the press strength and the shear strength are also researched. The calculating model about artificial ground freezing applying to a tunnel in shanghai is set forth. Some environment questions about artificial ground freezing are discussed. |
