Abstract In order to explore the evaluating method of infrared imaging detection technique(differences in thermal conductivity) for potassium silicate(PS) reinforced earthen ruins soil，adopting the disturbed soil collected from Jiaohe ruins to make soil models，which are reinforced by different concentration of PS，the mechanical strength and thermal conductivity of soil models were determined. It is shown that mechanical strength increase and thermal conductivity reduce for PS reinforced soil. Under the condition of the same dosage of PS，the larger the concentration of PS is，the higher the mechanical strength of soil is，but the smaller the thermal conductivity of soil is. Through analyzing the experiment data regression，thermal conductivity and strength has a good linear negative relationship. Finally，explore the alterative mechanism of thermal conductivity of soil in the effect of PS，describe the relationship between thermal conductivity and strength in the from microstructure of soil. The relationship above shows that thermal conductivity can be used to evaluate the reinforcing effects of earthen sites，which provides a possible method to carry out the non-destructive inspection of the effect for PS reinforced earthen ruins soil.

Key words： soil mechanics ruins soil potassium silicate(PS) materials thermal conductivity strength non- destructive inspection
