Advances in sensor platforms, including unmanned aerial vehicle (UAV)-based photogrammetry, light detection and ranging (LiDAR), and interferometric synthetic aperture radar (InSAR), have led to significant advances in terrain monitoring, rock mass characterization, and geohazard assessment. While these technologies improve data accuracy and accessibility, they also introduce challenges related to data processing and integration. This study discusses the advantages and limitations of active and passive remote sensing methods and emphasizes their role in engineering geological investigations. Based on short case studies, the study emphasizes the need for multidisciplinary approaches to fully exploit remote sensing data in engineering geology, ensuring more reliable and cost-effective infrastructure monitoring and hazard mitigation strategies.</p><p><b>Moderne Fernerkundungsmethoden in der Ingenieurgeologie zur Bauwerksprüfung und Charakterisierung von Gelände- und Gebirgsverhältnissen</b></p><p>Fernerkundungstechnologien haben die ingenieurgeologische Arbeit in den letzten zwei Jahrzehnten erheblich verändert und neue Wege für die geologische Kartierung und Bauwerksprüfung ermöglicht. Diese Studie gibt einen Überblick über die aktuellen Fernerkundungsmethoden für die ingenieurgeologische Praxis (z.B. UAV-basierte Photogrammmetrie, LIDAR und InSAR) und hebt deren optimale Anwendungsfälle zur Erfassung von Geländeveränderungen, Gebirgscharakterisierung und Naturgefahrenanalyse hervor. Die Fortschritte in Datenqualität und -verfügbarkeit, brachten jedoch auch neue Herausforderungen für die Datenverarbeitung und -visualisierung mit sich. Diese Studie fasst die Vor- und Nachteile aktiver und passiver Fernerkundungsmethoden zusammen und analysiert die jeweilige Bedeutung für ingenieurgeologische Anwendungsfälle. Der Schwerpunkt liegt dabei auf interdisziplinären Ansätzen, um das Potenzial von Fernerkundungsdaten in der Ingenieurgeologie auszuschöpfen und ein zuverlässiges und effizientes Infrastrukturmonitoring und Risikominderung zu gewährleisten.</p>","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"18 3","pages":"178-187"},"PeriodicalIF":0.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is notable for cost-effectiveness and versatility in achieving different tunnel profiles. Though the technique has advantages, it also has challenges such as overbreak, undercut, and occasional poor advances, which can increase project costs and delays. The outcome of blast results is also associated with the competency of driller in effectively drilling the planned holes. Hence, frequent and substantial modifications in the blast designs to attain good profile and pull can adversely affect the driller's performance, thereby reducing the desired outcome. This article presents a case study of the Sivok-Rangpo tunnels passing through different classes of rock mass (class III–VI). Minimum changes in cut pattern and periphery holes design were incorporated and found efficient in increasing the tunnel advance rate to 90–92 % of the drill hole length. The processes also reduced the overbreak and underbreak considerably.</p>","PeriodicalId":39412,"journal":{"name":"Geomechanik und Tunnelbau","volume":"18 3","pages":"218-224"},"PeriodicalIF":0.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
