“…GPR Borecka et al (2015) telah melakukan penelitian menggunakan metode GPR dengan frekuensi 100 MHz dengan potensi slip plane pada kisaran 3-10 m di bawah permukaan. Metode GPR dilakukan untuk interpretasi area bidang gelincir potensial dan hasil yang diperoleh tersebut secara signifikan terkait dengan hasil uji geoteknik yang dilakukan (Borecka et al, 2015). Penelitian yang hanya menggunakan metode GPR dinilai kurang efektif dalam menentukan potensi longsor, sehingga perlu dibarengi dengan metode pendukung lainnya untuk memverifikasi struktur bawah permukaan dengan baik.…”

“…Pada artikel ulasan disini, dilakukan pembahasan lebih mendalam mengenai metode GPR dalam berbagai aspek.Metode Ground Penetrating Radar (GPR) merupakan metode geofisika yang menggunakan analisis refleksi gelombang elektromagnetik berdasarkan perbedaan sifat dielektrik benda di bawah permukaan. Metode pencitraan bawah permukaan non-invasif ini dapat digunakan untuk mengkarakterisasi stratigrafi pada lapisan-lapisan di bawah permukaan bumi (Borecka et al, 2015). Metode GPR ini dikenal sebagai metode non-destruktif yang efektif untuk menentukan citra bawah permukaan yang dangkal (0 -10 m) dengan resolusi yang baik.…”

Pengujian dan diagnosis non-destruktif sangat populer, karena efektif untuk investigasi atau inspeksi bawah permukaan untuk dapat melakukan pemantauan, prediksi, dan pengelolaan dengan lebih tepat seperti halnya pemantauan kualitas dan kondisi jalan dan jembatan, hingga prediksi kestabilan, dan potensi longsor pada lereng. Pada penelitian ini banyak penelitian menggunakan metode Ground Penetrating Radar (GPR) karena kehandalannya dalam mencitrakan struktur lapisan dengan resolusi tinggi sesuai dengan frekuensi yang dibutuhkan. Artikel ini bertujuan mengkaji penerapan metode GPR dan Geoteknik untuk dapat mendeteksi kerusakan infrastruktur dan potensi longsor dengan berfokus pada penelitian terbaru dari tahun 2012 – 2022 yang dipublikasikan di jurnal internasional. Dalam dekade terakhir ini telah banyak dilakukan penelitian tentang evaluasi infrastruktur publik dengan karakteristik struktur lapisan jalan dan jembatan, deteksi retakan, dan stabilitas potensial, sedangkan pada penelitian longsor telah ditentukan parameter fisik dan bidang gelincir untuk menghitung faktor keamanan dan jangkauan jarak menggunakan metode geofisika, geoteknik dan kombinasi keduanya. Dalam studi kasus terbaru, para peneliti telah menggunakan kombinasi metode untuk mencapai hasil yang maksimal, karena metode yang digunakan akan saling melengkapi. Salah satunya menggunakan metode geoteknik dengan menggunakan data bor serta uji laboratorium berupa uji kuat geser, uji oedometer IL, uji triaksial CIU, dan CID untuk mendapatkan potensi longsor yang baik. Sedangkan untuk penilaian infrastruktur publik digunakan metode geoteknik berupa analisis numerik dan uji laboratorium sebagai data pendukung hasil yang diperoleh.

“…As reported in [17], geophysical techniques are widely used to detect subsurface properties, and study buried geometries and map landslide areas. Among the most widely used geophysical techniques employed to investigate landslides are seismic refraction, electrical tomography, passive seismic and ground penetrating radar (GPR) [14,16,[18][19][20][21][22][23][24][25]. These techniques are widely used because of their many advantages, despite some limitations.…”

Geophysical Surveys for Geotechnical Model Reconstruction and Slope Stability Modelling

Performing a reliable stability analysis of a landslide slope requires a good understanding of the internal geometries and an accurate characterisation of the geotechnical parameters of the identified strata. Geotechnical models are commonly based on geomorphological data combined with direct and intrusive geotechnical investigations. However, the existence of numerous empirical correlations between seismic parameters (e.g., S-wave velocity) and geotechnical parameters in the literature has made it possible to investigate areas that are difficult to reach with direct instrumentation. These correlations are often overlooked even though they enable a reduction in investigation costs and time. By means of geophysical tests, it is in fact possible to estimate the N-SPT value and derive the friction angle from results obtained from environmental seismic noise measurements. Despite the empirical character and a certain level of uncertainty derived from the estimation of geotechnical parameters, these are particularly useful in the preliminary stages of an emergency, when straight data are not available and on all those soils where other direct in situ tests are not reliable. These correlations were successfully applied to the Theilly landslide (Western Alps, Italy), where the geotechnical model was obtained by integrating the results of a multi-parameter geophysical survey (H/V seismic noise and ground-penetrating radar) with stratigraphic and geomorphological observations, digital terrain model and field survey data. The analysis of the triggering conditions of the landslide was conducted by means of hydrological–geotechnical modelling, evaluating the behaviour of the slope under different rainfall scenarios and considering (or not) the stabilisation interventions present on the slope. The results of the filtration analyses for all events showed a top-down saturation mechanism, which led to the formation of a saturated face with a maximum thickness of 5 m. Stability analyses conducted for the same events showed the development of a shallow landslide in the first few metres of saturated soil. The modelling results are compatible with the actual evolution of the phenomenon and allow us to understand the triggering mechanism, providing models to support future interventions.

“…The eigenpotential method is often used in conjunction with monitoring the resistivity of the landslide body [13]. Of great importance in obtaining information about the structure of the landslide under study are measurements made with GPR (Ground Penetrating Radar) [14]. Significant landslide areas are monitored with the participation of satellites [15].…”

The article presents a new research apparatus for measuring the electromagnetic activity of landslides. The basic element of the apparatus is a highly sensitive underground receiver of the magnetic component of the EM field. Such a receiver inserted to the full depth of a landslide well records the levels of magnetic field amplitude at a given depth. Anomalous levels of the magnetic component indicate the existence of landslide slip planes. Combining several receivers into a measurement system will enable continuous monitoring of landslide activity. The article presents examples of studies using the discussed apparatus, which were carried out on real landslides.
