Abstract
The presence of complex karst caves poses significant challenges to construction safety and progress in tunnel engineering. Undetected karst caves in front of tunnel faces pose a risks of sudden water influx disasters. We employed an advanced semi-airborne transient electromagnetic method (SATEM) to detect potential karst caves located in areas with undulating karst terrain. Additionally, we utilized a handheld Simultaneous Localization and Mapping (SLAM)-based LiDAR device to accurately and efficiently scan large exposed caves, providing support for the design of karst cave treatment plans. For different karst cave characteristics, we introduce a series of effective comprehensive treatment methods, including sealing, crossing, and filling strategies. We demonstrate, for the first time, the outstanding effectiveness of SATEM surveys in detecting highly resistive caves, with multiple successful predictions of dried-up caves in Linlan tunnel. The proposed SATEM detection and comprehensive treatment technical system not only ensures the safety of the construction of the Tian’e-Bama expressway but also provides profound insights and practical guidance for the field of karst tunnel engineering.
期刊介绍:
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
