“…The results show that ground-penetrating radar detection can be used to reduce the risk of long-term ground settlement. Alsharahi, Gamil, and others [31,32] used ground-penetrating radar to detect voids in soil and other circular objects with physical properties, electrical conductivity, and dielectric properties, and obtained their radar profiles and signal evolution diagrams. Li et al [26] described the data processing and interpretation methods, the detection methods of GPR, and their application in dam detection, and studied the dam body leakage problem.…”

Non-aqueous reactive polymer grouting technology has been widely used in the repair engineering of dikes and dams with shallow diseases. By using the finite difference time-domain method and perfectly matched layer boundary conditions, the calculation model of dikes and dams with shallow diseases such as water-filled cave, air-filled cave and incompact area is established. The propagation process of electromagnetic waves of ground-penetrating radar in dikes and dams with shallow diseases using polymer grouting repair is simulated, and the forward simulation profiles and single-channel waveforms are obtained. The propagation characteristics such as waveform amplitude, waveform shape, transmission time, and reflection time are compared and analyzed. The results show that the forward simulation profiles of dikes and dams with water-filled caves before and after polymer grouting repair present two clusters of hyperbolas, but three clusters of hyperbolas with different amplitudes were observed at 50% repair. The amplitude of the hyperbola and the single-channel reflected waves before repair and 50% repair of the cave and incompact area are greater than those of 100% repair. The propagation characteristics of ground-penetrating radar can effectively explain the degree of polymer grouting repair for dikes and dams with shallow diseases, and provide a theoretical basis for using the ground-penetrating radar to evaluate the effect of polymer grouting technology to repair dikes and dams with shallow diseases.

Öz Yere nüfuz eden radar (GPR), bir duvarın arkasına gizlenebilen veya duvarın içine yerleştirilebilen nesnelerin algılanması için kullanılan ultra geniş bantlı bir elektromanyetik sensördür. GPR yöntemi, arayüzde yer alan yüksek hızda bir anten tarafından yatay yönde yeraltına gönderilen elektromanyetik dalgaların, yine alıcı tarafından yatay yönde yansıtılmasının kaydedilmesi prensibi üzerine çalışır. Gömülü yapılar; toplanan veriler, bilgisayar programları ve çeşitli filtreler kullanılarak algılanır. Hava cepleri gibi duvarlar arasında gizlenmiş hedeflerin bulunması arkeologlara yardımcı olur. Bu çalışmada, toprağın dağılımı için Lorentz modeli kullanılmıltır. Sınır koşullarını sönümleyip açık bir alanı simüle etmek için mükemmel uyumlu katman (PML) kullanılmış ve dağıtıcı medyaya uyacak şekilde genişletilmiştir. Sonlu farklı zaman alanı (FDTD) yöntemi, elektromanyetik alanların zaman basamaklamasındaki kısmi diferansiyel denklemleri ayrıştırmak için kullanılır. FDTD hesaplaması çok yavaş çalışmaktadır. Bu sorunu çözmek için grafik işlem biriminde (GPGPU) genel amaçlı programlama yapılabilmektedir. Bu çalışmada GPU'ya CUDA kullanılarak 3-B FDTD yöntemi uygulanmış ve 10 kat hızlanmıştır.
