摘　　要：本文在理论与试验的基础上,深入地分析了温度对地下工程结构内外实测中静力传感器传感性能影响的诸因素。指出了传感器结构本身各部位材料温度系数的不同是造成静力传感器热输出的主要原因。提出了一种新的温度曲线校正法——综合校正法。Based on theoretic study and experiments, this paper thoroughly analyses the effect of temperature on the transmission property of static transducers used in in-situ measure of internal and external forces in Underground structures. It is pointed out that the heat output of static transducers results chiefly from the difference of temperature coefficients of all parts of which the transducer is composed. A new correction method of temperature curvesynthetic correction method is put forward
