“…After TDP is added to the analysis of the phase difference, in fact, the detection ability of the multichannel transient Rayleigh wave detecting method can be expanded to the ultrasonic frequency band. In addition, the method has achieved good results in the detection of weathering of white marble handrails in the Forbidden City [ 21 ].…”

Geological and hydrogeological conditions in karst areas are complicated from the viewpoint of engineering. The construction of underground structures in these areas is often disturbed by the gushing of karst water, which may delay the construction schedule, result in economic losses, and even cause heavy casualties. In this paper, an innovative method of multichannel transient Rayleigh wave detecting is proposed by introducing the concept of arrival time difference phase between channels (TDP). Overcoming the restriction of the space-sampling law, the proposed method can extract the phase velocities of different frequency components from only two channels of transient Rayleigh wave recorded on two adjacent detecting points. This feature greatly improves the work efficiency and lateral resolution of transient Rayleigh wave detecting. The improved multichannel transient Rayleigh wave detecting method is applied to the detection of karst caves and fractures in rock mass of the foundation pit of Yan’an Road Station of Guiyang Metro. The imaging of the detecting results clearly reveals the distribution of karst water inflow channels, which provided significant guidance for water plugging and enabled good control over karst water gushing in the foundation pit.

“…We simulate the records with 51 receivers evenly spaced (2 m) in line on the surface and the nearest offset of 40 m. As shown in Figures 4b and 5b, the two shot gathers are transformed into the f-v domain by high-resolution LRT. According to the relationship between penetration depths of Rayleigh waves and wavelengths [32], the surface waves of Model 3 and Model 4 cannot penetrate to a depth of 100 m, so the dispersion characteristics of pure surface waves in Figure 5a should be similar to those in Figure 4a. The surface waves shown in Figure 4a are not disturbed by the reflections from the deep reflectors.…”

It is essential to extract high-fidelity surface waves in surface-wave surveys. Because reflections usually interfere with surface waves on X components in multicomponent seismic exploration, it is difficult to extract dispersion curves of surface waves. To make matters worse, the frequencies and velocities of higher-mode surface waves are close to those of PS-waves. A method for surface-wave extraction is proposed based on the morphological differences between surface waves and reflections. Frequency-domain high-resolution linear Radon transform (LRT) and time-domain high-resolution hyperbolic Radon transform (HRT) are used to represent surface waves and reflections, respectively. Then, a sparse representation problem based on morphological component analysis (MCA) is built and optimally solved to obtain high-fidelity surface waves. An advantage of our method is its ability to extract surface waves when their frequencies and velocities are close to those of reflections. Furthermore, the results of synthetic and field examples confirm that the proposed method can attenuate the distortion of surface-wave dispersive energy caused by reflections, which contributes to extraction of accurate dispersion curves.

“…In engineering practice, there are many methods to evaluate the lining quality of long-distance pressure culverts. One such treatment method is nondestructive testing which is an effective and widely used method to ensure the safety of tunnel, such as the ground penetrating radar (GPR) [7][8][9], the multichannel analysis of surface waves (MASW) [10,11], the infrared thermography (IRT) [12][13][14][15], and the Rayleigh waves [16]. However, the results of nondestructive testing were different from the reality results in some special stratum conditions, and this illustrated that the method of nondestructive testing also presents some limitations.…”

It is of great significance to study the deformation characteristics of the lining of a long-distance pressure culvert. The lining of a pressure culvert has the characteristics of strong concealment and remarkable influence on the whole performance. The existing research on deformation characteristics mostly adopts nondestructive detection, and the accuracy is restricted by many factors. In this paper, the lining of a pressure culvert is taken as the research object, and in situ tests of the structure are carried out and numerical simulations are conducted. Based on field monitoring data, the mechanical and deformation responses of the lining structure under external water and earth pressure are analyzed. On this basis, the finite element method is used to establish a three-dimensional finite element model, which further analyzes the deformation and mechanical characteristics of the lining structure under different conditions of internal water pressure, geological conditions, and internal water pressure alongside geological conditions. Therefore, theoretical guidance and technical support for the lining structure design of long-distance pressurized water delivery culverts are provided.
