大直径混凝土灌注桩质量早龄期动力测试与分析

THE POWER TEST AND ANALYSIS OF THE QUALITY OF MAJOR DIAMETER CONCRETE -POURING STAKES IN THE EARLY STAGE

本文对大直径混凝土灌注桩质量早龄期动力测量的可能性,测试方法,桩身混凝土的成熟度计算进行了探讨,并根据试验资料提出了依据早期混凝土成熟度、实测弹性波速推算混凝土准抗压强度的方法和实用计算公式.

In this article, the author trys to probe into the possibility of the early stage power survey of major diameter concrete-pouring stakes, its testing method and the calculation of the concrete ripeness of the stake body . According to experimental data, he also puts forward the calculating method and practical calculation formula of the concrete quasi-compressive resistance on the basis of the early ripeness of concrete and the speed of elastic waves.
