【摘要】 在混凝土切割过程中，不可避免地会产生振动，严重的会使混凝土产生破坏，或使混凝土与钢筋骨架分离，影响结构混凝土的使用寿命。本文简述了在施工的同时用有效的手段对结构物进行动静态结合的现场检测，即应力－应变法测强及回弹法测强。检测结果表明，这种检测方法是行之有效的，应力－应变法测强这种精确的实验室检测手段可以用于现场检测。更多还原

【Abstract】 In cutting concrete,it is inevitable to produce vibration,In serious condition,the concrete will be damaged or separated from the rein-forced bars,so as to influence the service life of the concrete structure,In this paper, the combined on-site dynamic and static measurement一strength measurement with the stress-strain method and rebound method on the structure body under construction are briefly described.The measurement results show that these are effective measurement methods.The stress-strain method一the preciselab measurement method can be used for on-site measurement更多还原
