快速、非侵入性面波测量提供了深度剖面，可根据深度剖面生成用于土方工程条件评估的地面模型。土方工程的整个刚度控制着在静态和动态荷载下的行为，而表征非均质性与工程回填的稳定性和老化的公用设施和交通基础设施的生命周期恶化有关。连续面波方法被用来识别英国诺丁汉大中央铁路沿线端部路堤中细粒和粗粒之间的界面。采用表面波多通道分析(MASW)方法研究了约克郡埃格伯勒附近克诺廷利运河和古勒运河沿线运河堤坝中的地下排泄情况。目前正在使用MASW方法研究极端天气对拉弗顿附近格洛斯特郡-沃里克郡铁路沿线高塑性粘土路堤稳定性的影响。结果表明，使用该设备可获得最佳效果。
Rapid, non-intrusive surface wave surveys provide depth profiles from which ground models can be generated for use in earthwork condition assessment. Stiffness throughout earthworks controls the behaviour under static and dynamic loads, and characterising heterogeneity is of interest in relation to the stability of engineered backfill and life-cycle deterioration in aged utility and transportation infrastructure. Continuous surface wave methods were used to identify interfaces between fine- and coarse-grained fill in an end-tipped embankment along the Great Central Railway in Nottinghamshire, UK. Multichannel analysis of surface wave (MASW) methods were used to characterise subsurface voiding in a canal embankment along the Knottingley and Goole canal near Eggborough, Yorkshire. MASW methods are currently being used to study extreme weather impacts on the stability of a high-plasticity clay embankment along the Gloucestershire–Warwickshire railway near Laverton. Optimal results were obtained using equipme...
