Abstract

The project adopt raw materials of Shenyang subway tunnel lining concrete to product 40 groups of tunnel lining concrete specimen. First of all investigating and analyzing the corrosion of subway tunnel lining concrete.Second determine the selection of sodium sulfate on tunnel lining concrete under dry-wet alternate accelerated corrosion test.The corrosion of tunnel lining concrete in the process of performance change was described. Through the non destructive testing(NDT) of rebound method detecting the strength of tunnel lining concrete after corrosion of sodium sulfate.We got mean relative error( ) and relative standard error ( ) inside the specification through linear function, power function and exponential function, quadratic polynomial function regression analysis on non destructive testing and damage testing. The regression results show that strength test curve has good applicability to the corrosion of tunnel lining concrete.Raising the strength formula of shenyang subway tunnel lining concrete subjected to corrosion test.
