摘要
利用数理统计中假设检验思想分析早期振动对混凝土强度产生影响的变化范围,确定产生影响的对比强度变化率计算公式。并根据混凝土强度发展的规律,提出采用混凝土强度变化趋势的对比强度趋势变化的分析方法来评价早期振动对混凝土强度的影响。
The variation range of the influence of early vibration on the strength of concrete is analyzed by means of hypothesis testing in mathematical statistics.The formula for calculating the rate of change of contrast intensity is determined.A new analysis method based on the law of concrete strength development is presented to evaluate the influence of the early vibration on the strength of concrete.
