针对某隧道衬砌混凝土产生膨胀、剥落和软化的质量问题，通过对混凝土所用原材料、水文地质环境和气候条件的调查，结合原材料试验和腐蚀物的XRD相关数据，分析混凝土腐蚀过程以及侵蚀机理。研究表明，碳硫硅钙石侵蚀是引起混凝土腐蚀的主要原因，应引起高度重视。

Aiming at the quality problem of concrete expansion,spalling and softening,through investigation on the mixing materials,the hydro-geology condition and climatic characteristics of a certain tunnel,also connected with the results of material testing and XRD of the corrosion products,analyzed the corrosion mechanism and corrosion process. Researches showed that the corrosion of lining concrete was caused by TSA attack,which should be attracted great attention.
