（浙江大學(xué)土木系 杭州 310027）[提要] 著重分析了《混凝土結(jié)構(gòu)工程施工及驗(yàn)收規(guī)范》( GB50204-92)在高強(qiáng)混凝土質(zhì)量檢驗(yàn)和驗(yàn)收中存在的問題。采用勻質(zhì)性指標(biāo)（變異系數(shù)）分析，提出了高強(qiáng)混凝土質(zhì)量檢驗(yàn)和驗(yàn)收標(biāo)準(zhǔn)，很好地解決了規(guī)范中對平均強(qiáng)度要求過高或過低，而最小強(qiáng)度要求又偏低的突出矛盾。既簡化了驗(yàn)收標(biāo)準(zhǔn)，又實(shí)現(xiàn)了驗(yàn)收標(biāo)準(zhǔn)隨著混凝土強(qiáng)度等級提高而同步提高的目標(biāo)。
[關(guān)鍵詞] 質(zhì)量檢驗(yàn) 高強(qiáng)混凝土 混凝土The problems existing in the qualities checking and acceptance of high strength concrete structure( HSCS) using Code for Construction and Accepance of Concrete Structures (GB50204-92) have been studied. Depending on the analysis of index of ruuformity (coefiicient of variation), the standard of quality checking and acceptance for HSCS has been delivered. The contradiction which consists in the code, exorbitant or lacking average strength requesting, and over-low mirumum strength requesting, has been solved. The acceptance index is simplified and the acceptance standard would be raised with the concrete strength grade rising.
Keywords: quality acceptance; high strength concrete structure; concrete
