In view of the shortcomings of the hole for measuring temperature in monitoring the

temperature field of freezing wall and the peculiarity of the high density resistivity method，this paper

studied the feasibility of applying the high density resistivity method to monitoring the temperature

field of freezing wall. Under the condition of initial water content and density of the test soil similar to

that of the undisturbed soil，the electrical conducting characteristics of silty soil in No.4 Line of

Shanghai Metro System were studied with three resistivity methods (Wennerα、Wennerβ and

Wennerγ) at 30～-30℃. Some phenomena have been observed:  First，trends between the variation

of apparent resistivity and the variation of the temperature by three high density resistivity methods are

very consistent，namely， apparent resistivity of silty soil will augment（or electrical conducting

characteristics will become weak）when its temperature falls，and electrical conducting

characteristics are close to temperature；second，when temperature overtops -4℃，the range of

resistivity diversification of silty soil is relatively narrow when temperature changes；thirdly， when

temperature is below -4℃，the resistivity of silty soil will change obviously when temperature changes

；fourthly，three high fitting degree regression equations of temperatureresistivity were fitted, they

were applicable to 30℃≥t>-4℃，-4℃≥t>-10℃，-10℃≥t≥-30℃ respectively by each high density

resistivity method. All the above results show that the high density resistivity method is suitable for

monitoring the temperature field of freezing wall，and can provide a reference for testing the

development of freezing wall in similar soil layers when the artificial ground freezing method is

employed in Shanghai and even the Yangtze River Delta.
