摘要
文章采用干湿交替加速腐蚀的试验方法,研究了沈阳地铁隧道衬砌混凝土在硫酸盐腐蚀后的抗压强度,并将回弹值、超声波波速两种无损检测参量与破损参量用于抗压强度回归分析,提出沈阳地铁隧道衬砌混凝土受硫酸盐腐蚀后的测强曲线公式。
By using the accelerated corrosion experiment method of wetting-drying cycles, this article studied the compressive strength of Shenyang subway tunnel lining concrete after sulfate corrosion, where two kinds of non-destructive testing parameters and damage pa- rameters, i.e.rebound value and ultrasonic velocity, were used for compression strength re- gression analysis,and it proposed the strength curve formula for Shenyang subway tunnel lining concrete after sulfate corrosion.
