本文以南美洲秘鲁某港口用混凝土联锁块耐磨性参数检测实例,将同一块混凝土联锁块加工为两个样品,分别采用中国标准《GB 12988-2009无机地面材料耐磨性能试验方法》及英国标准《BS EN 1338:2003 Concrete paving blocks:Requirements an...本文以南美洲秘鲁某港口用混凝土联锁块耐磨性参数检测实例,将同一块混凝土联锁块加工为两个样品,分别采用中国标准《GB 12988-2009无机地面材料耐磨性能试验方法》及英国标准《BS EN 1338:2003 Concrete paving blocks:Requirements and test methods》进行耐磨性试验,共90组样品。采用SPSS分析数据,结果表明:两种方法得出的试验结果具有极强相关性,回归方程为Y=1.73+0.46*X,相关系数为0.822。展开更多
通过对比中英标准中关于裂缝计算的过程,分析两种标准在混凝土结构设计中环境类别的划分,裂缝控制等级和裂缝计算参数上的差异。对比两种标准可知:英国标准对环境类别,环境作用等级进行独立划分,使其更为明确详细;中国标准对于裂缝宽度...通过对比中英标准中关于裂缝计算的过程,分析两种标准在混凝土结构设计中环境类别的划分,裂缝控制等级和裂缝计算参数上的差异。对比两种标准可知:英国标准对环境类别,环境作用等级进行独立划分,使其更为明确详细;中国标准对于裂缝宽度的要求明显高于英国标准;中国标准与英国标准关于裂缝计算都是基于粘结滑移–无滑移理论,但英国标准中涉及到的参数最多,各种影响因素考虑的最为全面。By comparing the crack calculation process in the Chinese and British standards, the differences in the classification of environmental categories in concrete structure design, crack control levels and crack calculation parameters in the two standarsds are analyzed. Comparing the two standards, it can be seen that the British standard divides environmental categories and environmental action levels independently, making them more clear and detailed;the requirements for crack width in the Chinese standard are significantly higher than those in the British standard;both the Chinese and British standards are based on the bond slip-no slip theory for crack calculation, but the British standard involves the most parameters and considers various influencing factors most comprehensively.展开更多
