【摘要】：環(huán)境介質(zhì)對于地下洞室混凝土的腐蝕將影響其耐久性。采用現(xiàn)場探查、測量以及取樣分析方法,對宜興抽水蓄能電站地下廠房洞室混凝土酸性腐蝕狀況進(jìn)行了綜合測試與評價(jià)。結(jié)果表明,區(qū)內(nèi)洞室局部混凝土已遭受了不同程度的腐蝕作用�？梢园哑浞譃�3類:Ⅰ類為未受到(或極輕微)腐蝕;Ⅱ類為已受到較弱腐蝕;Ⅲ類為已受到相對嚴(yán)重腐蝕。同Ⅰ類相比較,Ⅱ和Ⅲ類的基本組分含量已發(fā)生了變化,即其中的硫、鐵及堿性物質(zhì)含量趨于增加,鈣質(zhì)則趨于減少;而在Ⅲ類的礦物相中,還含有石膏類次生礦物相。
[Abstract]:The corrosion of underground cavern concrete by environmental media will affect its durability. The acid corrosion status of concrete in underground powerhouse of Yixing pumped Storage Power Station was comprehensively tested and evaluated by site exploration, measurement and sampling analysis. The results show that the local concrete in the cavern has been corroded to some extent. It can be divided into three categories: type I is uncorroded (or very slight), class 鈪，
