摘要
根据目前常用的超声波推算灌注桩混凝土的强度公式及修正系数，探讨了混凝土龄期、养护环境对灌注桩混凝土强度的影响，并提出了修正方法。
In view of ultrasonic method normally used in strength calculation of bored concrete pile its calculation formula and correction factors are introduced. From age of concrete and maintenance conditions factors influencing the strength of concrete are discussed; at the same time related correction factors are proposed.
