复杂地层差异冻结研究分析
Analysis of freezing difference in complex strata
摘要
Abstract
In this paper,the freezing temperature field in the freezing process of single freezing tube in Xinzhuang is analyzed by field measurement and simulated freezing analysis,and the freezing temperature field of the complex stratum is discussed with the difference freezing theory,and the following conclusions are drawn:(1 )The deeper the stratum is,the greater the thermal physical parameters are caused by the change of temperature;(2)Due to the change of the freezing efficiency of the strata,the thickness of the frozen wall will be changed greatly,(3)The freezing temperature can be adjusted in real time according to the different freezing strata and freezing temperature.Thus,the freezing circle of the strata with poor freezing efficiency in-creases and the thickness gap of the frozen wall decreases,thus improving the safety and economy of the freez-ing project.关键词
