在对广州某施工现场进行混凝土回弹试验的基础上，采用χ2检验法对现场采集到的混凝土抗压强度选取正态分布进行检验，本文分析 C50混凝土推定抗压强度的概率统计规律，计算结果表明，施工现场的 C50混凝土推定抗压强度的概率分布服从正态分布，与规范中 C50混凝土抗压强度的均值，变异系数相比，该 C50混凝土抗压强度的离散型较小。
在對廣州某施工現場進行混凝土迴彈試驗的基礎上，採用χ2檢驗法對現場採集到的混凝土抗壓彊度選取正態分佈進行檢驗，本文分析 C50混凝土推定抗壓彊度的概率統計規律，計算結果錶明，施工現場的 C50混凝土推定抗壓彊度的概率分佈服從正態分佈，與規範中 C50混凝土抗壓彊度的均值，變異繫數相比，該 C50混凝土抗壓彊度的離散型較小。

On the basis of the concrete compressive strength test in GuangZhou,the ex-penimental data of concrete compressive strength were studied by Normal Distribution,the distribution were examined by χ2 mothed.This paper ana-lyzes the laws of probability and statistics cube compressive strength of con-crete,The result shows that C50 concrete compressive strength submits Nor-mal distribution,Compared with the mean and coef icient of variation of the compressive strength of concrete C50 in specification,the mean of the C50 concrete compressive strength is large,discrete is smal .
