| 摘 要： | 从频率特性和现场环境下的可操作性等方面优化震源激发方式,决定各部分设备的类型和技术指标,优化检波器设置方式以及检波器阵列组合关系,决定适合隧道快速无损检测的设备和施工方法,对天津市引滦入津输水隧洞进行现场表面波勘探检测.通过现场取样、室内样品测试,研究各种混凝土配合比下的弹性波速度和单位体积强度对应关系.对现场检测结果和现场取样结果进行对比分析,综合判断1~2 m范围内混凝土的劣化、剥离、围岩松动以及是否形成了空洞,最终建立表面波勘探无损检测法的判别标准.结果显示,该方法穿透深度大、不受钢筋影响,能够快速、准确地进行隧道混凝土质量的检测.

| Abstract: | A surface wave method for nondestructive test of concrete was developed to provide a 2-D image of the distribution of shear wave velocity.Because the shear wave velocity can reflect the strength of the concrete better,this method provides more important information for quality control during construction and for management during its operation.This method was applied to an investigation of concrete lining of a water tunnel.The results show that this method is fast and effective.Also,with a few laboratory te... |
