“…Several important highways connecting eastern and western China, including the G109 national Highway and the Zhangjiazhuang tunnel, cross this area (Figure 1c). The construction of the Zhangjiazhuang tunnel in this region started in 2010 and was completed in early 2012 [8]. But the Zhangjiazhuang tunnel was closed twice, on 18 January 2016 and 25 December 2018, respectively [41].…”

“…But the Zhangjiazhuang tunnel was closed twice, on 18 January 2016 and 25 December 2018, respectively [41]. The study area lies in a transition zone between the Qinghai-Tibet Plateau and the Loess Plateau, where there are active tectonic and frequent earthquake events [8,42]. Two subparallel strike-slip faults located on both sides of the entrance and exit of the Zhangjiazhuang tunnel (Figure 2) control the formation of the hills and valleys in the study area [8].…”

“…Landslides are distributed throughout the mountainous areas of western China [6,7]. In the transition zone between the Qinghai-Tibet Plateau and the Loess Plateau in particular, tectonics are active, the regional stability is fragile, and geological disasters are frequent [8]. Therefore, early identification and long-term monitoring of landslides are urgent tasks to provide scientific reference for landslide prediction, early warning, and preventative measures [9].…”

Information about the long-term spatiotemporal evolution of landslides can improve the understanding of landslides. However, since landslide deformation characteristics differ it is difficult to monitor the entire movement of a landslide using a single method. The Interferometric Synthetic Aperture Radar (InSAR) and pixel offset tracking (POT) method can complement each other when monitoring deformation at different landslide stages. Therefore, the InSAR and improved POT method were adapted to study the pre- and post-failure surface deformation characteristics of the Gaojiawan landslide to deepen understanding of the long-term spatiotemporal evolution characteristics of landslides. The results show that the deformation displacement gradient of the Gaojiawan landslide exhibited rapid movement that exceeded the measurable limit of InSAR during the first disaster. Moreover, the Gaojiawan landslide has experienced long-term creep, and while studying the post-second landslide’s failure stability, the acceleration trend was identified via time series analysis, which can be used as a precursor signal for landslide disaster warning. Our study aims to provide scientific reference for local governments to help prevent and mitigate geological disasters in this region.

“…Zhang et al (2017) analyzed the interaction between tunnel and landslide in mountain area, and studied the minimum safety distance between tunnel vault and sliding belt and its influence factors on the base of the slip-line theory. Zhou et al (2020) analyzed the structural damage of tunnel concrete and sidewalls induced by loess landslide and investigated the landslide deformation. The interaction between a slow-moving landslide in clay soil and a railway tunnel protected by sheet pile walls, which goes through the landslide accumulation, was presented by long-term deformation and stress monitoring and FEM modelling (Vassallo et al 2016, Mishra et al 2017, Minardo et al 2018, Vassallo et al, 2019.…”

The axis of highway tunnels constructed in mountains under complex geological conditions is usually orthogonal to the section of potential landslide. The tunnel construction may lead to landslide, which then may result in the deformation and/or cracking of tunnels. Therefore, it is very important and practical for tunnel projects to study the complex interaction mechanism between orthogonal tunnel and landslide and provide appropriate prevention measures for tunnel. This paper, on the base of geological survey, on-site monitoring and numerical simulation, analyzed the deformation and reason of an ancient landslide revived by tunnel construction and studied the prevention measures for tunnel. The results show that the reason for the revival of the ancient landslide resulted mainly from the tunnel construction through sliding surface, and the ancient landslide is generally stable because most landslide deformation occurred beyond the tunnel and in the upper part of landslide. The numerical simulation was used to optimize the tunnel prevention scheme by the analysis to the stability, stresses and deformation of landslide based on stress-strain control theory. The original anti-slide pile design was cancelled and finally the tunnel is reinforced by upper soil removal and moving upper soil into toe. This tunnel has successfully completed and are under good operation. The used prevention measures were proven to be effective according to the monitoring data about displacements and stress of landslide and tunnel during operation period, and saved about seven million US$. The research results in this paper may offer a beneficial reference to projects with similar geological conditions.

“…The instantaneous load caused by a collapse could cause devastating damage to a building located below the slope. Similarly, the stress redistribution generated after a collapse will change the stress state of the original supporting structure and could cause further damage (Konagai et al 2005;Zhang et al 2017;Vassallo et al 2019;Zhou et al 2020). In comparison with a landslide, the geological hazard represented by the combination of a slope and tunnel is more complex.…”

Loess has the characteristic of orthotropism and it forms landforms with isolated soil columns and vertical slopes on the Loess Plateau in China. Under the influence of various geological processes, collapse disasters can occur easily and induce secondary geological hazards. Based on the collapse in the Fen River drainage basin in 2019, a laboratory study was conducted to reverse engineer the collapse development, and the impact of the collapse on adjacent structures was studied. In this paper, the deformation, stress, and moisture of the slope model are monitored by using sensors and a 3D laser scanner. In addition, the deformation of tunnel structure and the cracking of tunnel are monitored. The effect of slope collapse on tunnel structure is analyzed according to soil strength theory, and the tunnel deformation is calculated theoretically. The study clarified the development characteristics of loess collapse and its mechanism of action on adjacent tunnels, which has important guiding significance for disaster prevention, engineering, and environmental protection on the Loess Plateau and other similar areas.
