研究地质

The Altai Paleozoic orogenic belt of Xinjiang Autonomous Rejoin is geologically wellknown both domestic and abroad by the intensive development of low-pressure metamorphism and granitic magmatism. Within pelitic metamorphic rocks, even though sillimanite is well developed and the low-pressure minerals like andalusite and cordeirite etc. are quite common, the assemblage of garnet and staurolite is more important.

This article analyses the application conditions of freezing method, current research status and the problems in this field. It points that it's necessary to study deep freezing temperature field deeply and discusses the factors which influence the freezing wall such as soil's nature, moisture content, geological conditions, etc. It introduces the theory, process of freezing method, the distribution of temperature field of freezing method and key thermotics parameters influencing freezing temperature field. It simplifies the deep freezing temperature field model. Through ANSYS, this article founds the deep freezing temperature field model, and simulates the field on vary heat conductivities. It analyzes the results of ANSYS simulation, gains the theoretical value of thermometric holes which is needed by back-analysis. Using the simulation temperature and actual value, it gets the equivalent heat conductivity. Then it solves the deep freezing temperature field by the equivalent value, simulates the freezing wall development process and temperature change curve. Against the actual project, the results are favorable.
