摘要
为了对预应力混凝土梁孔道压浆效果进行准确评定,研究确定有效的无损检测技术十分重要。对声波散射法的检测原理和方法进行了研究,并选取某梁场4片预应力混凝T梁进行了相关试验,根据对试验数据的分析,得到了压浆效果评定的有关结论并提出相关建议。
To evaluate the pore grouting system for the prestressed concrete beam in an accurate way, it is vitally important to develop an effective non -destructive testing technology. In this thesis, test principles and methods of acoustic scattering have been studied. Four pieces of prestressed concrete T - shape beams are chosen to be the experimental subjects. According to the test data, the relevant conclusion of evaluation on the grouting effect has been achieved and relevant suggestions are provided.
