经典单排管冻结温度场的瞬态适用性研究

Study on the Transient Applicability of the Temperature Field in the Classical Single-Row-Tube Freezing

在冻结法施工过程中,对于冻土温度场的研究非常重要。很多学者根据理论和实践推导出一些用于分析温度场的公式,但目前的研究还主要集中在温度场的稳态分析,对于温度场的瞬态分析研究较少。该文通过对经典巴霍尔金单排管公式的瞬态分析,将巴氏公式计算的结果同瞬态数值模拟结果进行比较,进而探讨影响巴氏公式在冻结过程中的准确性和适用性,以便实际工程选用参考。

During the construction process of the freezing method,it is very important to study the temperature field of the frozen soil.Many scholars have derived some formulas for analyzing the temperature field in light of a theoretical and practical ground.However,the present research largely focuses on the steady-state analysis of the temperature field,and few on the transient analysis.This paper conducted a transient analysis of the classical Baholkin formula for single-row tubes,and then compared the results calculated by this formula with the transient numerical simulation results,further exploring what can impact the accuracy and applicability of the formula in the freezing process,so that it can be used for reference in practical projects.
