【摘要】：首次将压电陶瓷弯曲元测试技术引入到高聚物注浆材料小应变动剪切模量测试中,制定了高聚物注浆材料弯曲元动剪切模量G_(max)的试验方案并制作了试验模具,确定了弯曲元设备对高聚物注浆材料的激发脉冲频率;探讨了高聚物注浆材料密度和弯曲元激发脉冲频率对G_(max)的影响,对比分析了高聚物注浆材料的动、静弹性模量,并讨论了高聚物注浆材料动剪切模量与土石料动剪切模量的相关性.试验得出的高聚物注浆材料动力学特性可为其动力反应分析和工程应用提供理论依据与参考.
[Abstract]:For the first time, the piezoelectric ceramic bending element testing technique was introduced into the testing of small strain shear modulus of polymer grouting materials, and the test scheme of dynamic shear modulus of polymer grouting materials was established and the test mould was made. The exciting pulse frequency of bending element equipment on polymer grouting material is determined, the influence of density of polymer grouting material and bending element excitation pulse frequency on GSP max) is discussed, and the dynamic and static elastic modulus of polymer grouting material are compared and analyzed. The correlation between dynamic shear modulus of polymer grouting material and dynamic shear modulus of soil and stone is discussed. The dynamic characteristics of polymer grouting materials can provide theoretical basis and reference for dynamic response analysis and engineering application.
