Abstract In situ measurement of corrosion rate of mild steel and soil factors has been carried out in Shenyang soil site.It showed that soil conductivity and soil salt content ，corrosion rate of mild steel increased wit h the raising of soil temperature.At the time of alternate spring and summer (f rom April to July),on account of underground temperature and soil conductance ri sing acutely,corrosion rate of mild steel was the highest.The error of copper be tween the in-situ corrosion and soil natural corrosion was not high,and the erro r reduced gradually with the extension of the test period.Therefore,the instrume nt of soil corrosion can measure quickly the corrosion rate of mild steel in-sit u.

Key words: mild steel soil corrosion in-situ
