摘要： 基于天津中央大道海河沉管隧道工程的大型试验模型，利用表面波勘探技术检测其混凝土管段水下注浆基础的施工效果，从频率特性和现场环境等方面选择表面波勘探设备的类型和技术指标，优化检波器的设置和排列组合方式，开发了适合快速无损检测隧道的设备配置和施工方法.通过现场表面波勘探和频散分析，综合判断隧道底部注浆的密实效果，并与模型撤离后的目测结果进行比较，以验证该勘探技术和分析方法的可行性.结果表明，表面波勘探方法的穿透深度大且不受钢筋影响，能够快速、准确地检测沉管隧道的注浆质量.

Abstract: Based on large-scale test model of the Haihe immersed tube tunnel locating at the centre avenue of Tianjin city, the application study of surface wave survey method, used for detecting filling effect of its underwater pressure casting foundation, was carried out. Considering the frequency characteristic and site environment of the tunnel, the types and qualification of equipments for surface wave survey were selected, setup and arrangement of detectors were optimized, and the equipment configuration and construction practices of fast nondestructive testing for tunnels were developed. The filling effect of mudjack method on tunnel foundation was estimated synthetically by surface wave survey in-situ dispersion and inverse analysis. Moreover, comparing the visual results when the test model removed, the practicability of this new survey techniques and analysis methods was verified. The test results show that this surface wave survey method can detect thick concrete filling without influence of reinforcing bars, and detect mud-jack method filling effect of immersed tube tunnel fast and correctly.

Key words: surface wave survey, immersed tube tunnel, grouting quality
