摘要

摘要: 针对季节性冻土冰锋面结构非接触识别问题，在对季节性冻土结构变化规律及物理力学性质分析的基础上，提出一种基于平行板电容传感器的季节性冻土冰锋面识别方法。该方法通过模拟季节性冻土温度变化，可给出不同温度下季节性冻土电容变化规律，并基于Boltzmann函数建立了季节性冻土电容与温度变化的数学模型。不同温度下测试得出季节性冻土中电容随温度的升高而逐渐增大，最终趋于常值；温度在-4~4℃，季节性冻土的电容随温度变化速率较快；季节性冻土处于较低负温状态和完全处于正温状态时，电容基本稳定。针对冻土区、冰锋面处、融土区的试验可得出，该方法可以有效地识别和分析季节性冻土冰锋面结构及其变化规律，误差在10%以内。

Abstract: A method for identifying ice front in seasonally frozen soils based on parallel plate capacitors was proposed to realize non-contact identification of the ice front structure based on analysis of variable structure laws and physico-mechanical properties of seasonally frozen soils. Particularly, a mathematical model was proposed for the relations of the capacitance and temperature of frozen soils based on the Boltzmann function, in which temperature variations of seasonally frozen soils were simulated to obtain capacitance responses in seasonally frozen soils at different temperatures. The results indicated that capacitance was gradually increased with temperatures and approached a constant value at a certain temperature. It was found that capacitance varied rapidly in the range of -4 to 4℃ and when temperatures of seasonally frozen soils were out of that range,it basically remained constant. The experiment showed that the developed method could efficiently determine ice front structure and obtain the variation trends of seasonally frozen soils within errors of 10% in the frozen, ice front and melted zones.
