摘　　要：通过嘉峪关地区早期推定混凝土强度试验,分别采用线性、幂函数回归方法建立强度关系式,并以实际工程进行了验证和应用,结果表明,两种强度关系式均能满足混凝土质量控制和配合比调整的要求,但线性方程计算简单,应优先采用。Through the test of early estimating strength of concrete in Jiaynguan area. Separately using a linear, power function regression method set up relationship of strength, and carried out a validation and application. The results show that two relationship of strength are able to meet the concrete quality control and adjust of mixing ratio. However, the linear equation is easy, priority is used.
