“…Поверхностно-волновая томография позволяет получать 3D-модели среды, обладает потенциально лучшим пространственным разрешением, чем широко используемый метод обработки поверхностных волн MASW . Перспективы использования метода связаны также с возможностью удаленного изучения, не требующего размещения приборов непосредственно над исследуемой зоной (расстановка приемников и источников проводится на удаленных профилях, частично или полностью совпадающих с периметром зоны) (Alyousuf et al, 2017). Поверхностно-волновая томография может быть также эффективной при проведении площадных инженерно-геофизических исследований на морском шельфе с донными станциями , поскольку позволяет расставить регистрирующие устройства по периметру площадки небольшого размера (например, 500 × 500 м), а затем выполнить отстрел.…”

The upper part of the seismic section is studied using refracted waves, as well as surface waves using the MASW method during engineering seismic surveys. This work is devoted to consideration of a relatively new near-surface approach, which is actively used in seismology for studying the upper mantle and deep part of the earth's crust, the method of surface wave tomography. This method is of great practical interest, since it allows to obtain 3D subsurface models and conduct remote researches; also it potentially has better spatial resolution than the widely used MASW method. Within the framework of this work, tests of the developed algorithm for surface-wave tomography using direct rays were carried out on modeled data. The performance of the algorithm was assessed and the resolution of the method was estimated. Also the optimal observation schemes were considered as well as the influence of the regularization parameter value on the inversion result. Basing on the results of the current study, it can be concluded that the method of surface-wave tomography and its realization via the developed algorithm can be effectively used to solve engineering-geological problems.

In this paper, we present the workflow of the application of surface wave tomography to characterize the near surface. A near surface model is simulated with a shallow unconsolidated layer that has a variable thickness and a deep consolidated zone. Data is filtered by bandpass filters and surface wave phase arrival times are picked, and surface wave velocities are inverted using a ray theoretical tomographic approach. A good agreement is found between the inverted results and the original model. In another model, a thin fault zone is detected. Agreement between the tomographic results and the model suggests that surface wave tomography is well suited for characterizing shallow geology with the capability of identifying low velocity anomalies and general lateral variations.
