摘　　要：水利建设中的河道护岸混凝土块体是水利建设项目中安全防护的基础结构,但目前对其抗压强度检测及质量检测、控制方法方面,还没有一种可直接参照的规范与标准。在传统的检测方式上,如采用等密度的振动模制法和钻孔取心的方法,已不能适应目前的要求。本文提出的实体切立方实验法,将功能性采样的真实感与时效性、试样与块体模塑的相容性、密实感与养护条件等有机结合,并与传统的湿法混凝土试件制备方法类似。由此得出的试验数据能更好地反映出砌块的实际强度,具有一定的合理性和普适性。该方法适用于不同规格、不同型式的干法混凝土块体的强度检测,具有较好的实用价值和推广价值。The concrete block for river bank protection in water conservancy construction is the basic structure for safety protection in water conservancy construction projects.However,currently,there is no direct reference specification or standard for its compressive strength testing,quality testing,and control methods.In traditional detection methods,such as using equal density vibration molding method and drilling and coring method,it can no longer meet the current requirements.The solid cube experimental method proposed in this article combines the realism and timeliness of functional sampling,the compatibility between sample and block molding,the compactness and curing conditions,and is similar to traditional wet concrete specimen preparation methods.The experimental data obtained from this can better reflect the actual strength of the block,which has a certain degree of rationality and universality.This method is suitable for strength testing of dry concrete blocks of different specifications and types,and has good practical and promotional value.
