The Himalayan region is known to be characterized by a complex and dynamic geological setting combined with high seismicity. A deep understanding of the engineering properties resulting from local geological processes of the region is a prerequisite to perform comprehensive design of geotechnical structures in the region, viz., landslide mitigation, slope stabilization, earth retention structures, etc. This paper presents a case study that highlights the engineering challenges that were encountered and the innovative design approach that was adopted to design a reinforced soil structure for construction of the Ventilation Tunnel Platform which is a critical and integral part of the Z-Morh tunnel in Sonamarg, Jammu and Kashmir, India. The innovative design philosophy, environmentally sustainable construction practices that were adopted and commentary on the finished structure are presented to validate the performance and functional advantages provided by the technology. The structure was commissioned in 2021 and its superior performance is well documented.

摘要

The Himalayan region is known to be characterized by a complex and dynamic geological setting combined with high seismicity. A deep understanding of the engineering properties resulting from local geological processes of the region is a prerequisite to perform comprehensive design of geotechnical structures in the region, viz., landslide mitigation, slope stabilization, earth retention structures, etc. This paper presents a case study that highlights the engineering challenges that were encountered and the innovative design approach that was adopted to design a reinforced soil structure for construction of the Ventilation Tunnel Platform which is a critical and integral part of the Z-Morh tunnel in Sonamarg, Jammu and Kashmir, India. The innovative design philosophy, environmentally sustainable construction practices that were adopted and commentary on the finished structure are presented to validate the performance and functional advantages provided by the technology. The structure was commissioned in 2021 and its superior performance is well documented.
