Abstract: Shaft sinking by freezing method of shaft lining in our country has reached more than 1100, engineering quantity, and get the relatively rich practical experience. The freezing method construction of inclined shaft is only more than 30, an engineering example, lack of construction experience, the technology research of inclined shaft freezing is less.In recent years, because of slope development is simple in equipment, such as large transport capacity advantages, is widely applied in the western region in China. Due to the geological conditions, using the freezing method construction of inclined shaft is becoming more and more pressing for construction of inclined shaft freezing study and discusses the basic theory, this paper takes Pang Pang freezing engineering for the model of inclined well of the tower is different depth (pressure), frozen wall thickness, different intensity of frozen wall and the numerical calculation between the deformation of borehole wall, explore the relationship between the variables and the size of the impact, to provide guidance for slope design and construction of freezing,.The basic research of inclined shaft freezing scheme comparison and optimum design, saving energy and reducing consumption has important reference value.
