“…The Yungang Grottoes, Mogao Grottoes in Dunhuang and Longmen Grottoes in Luoyang are known as China's three largest ancient grottoes; they are famous as world cultural heritages. Under the action of long-term natural forces, the surrounding rock of these grottoes has suffered numerous serious geological diseases (Guo, 2009;Li, 2016;Liu, 2012).…”

The Yungang Grottoes, a World Heritage Site in Datong, consist of 252 caves that are noted for their collection of 5th and 6th century Buddhist grotto sculptures and reliefs. Various diseases have appeared in the grottoes under the general influence of natural and artificial factors. Bolt support is a commonly employed method for grotto reinforcement and has been widely applied in many projects. Small-diameter bolts have also been used in the reinforcement projects at the Yungang Grottoes, but the corresponding effect on the seismic performance of grottoes is still unclear. In this paper, a dynamic analysis via the numerical modelling of an ear grotto of the 19th grotto in Yungang was established, and the rock displacement, acceleration and bolt axial force responses under a seismic wave are analyzed. The results show that the seismic dynamic responses of grottoes are greatly affected by the cliff structure. The displacement and acceleration responses of the cliff body vary greatly within the abrupt transition of the cliff structure. Based on this variation, the seismic capacity of small-diameter bolts in the vertical direction is greater than that in the horizontal direction. The axial force of a bolt is small at both ends of the bolt, large in the middle of the bolt, small on the top of a cliff and large at the bottom of the cliff. Although the axial force is small, the upper rock mass of the grotto has a tendency to undergo relative movement compared with the outer rock mass. The results also indicate that based on the structural defects in the vertical direction of the cliff body caused by grotto excavation, the inclined angle of the bolt should be increased as far as possible or vertical support should be adopted to enhance the stability of the rock mass at the top of the grotto.

“…The Gobi, atop the caves, was the secondary mesa in front of the mountain, dating from the quaternary period's Jiuquan group (Guo et al, 2009) as shown in Figure 1. The mesa was 30 to 40 m in height with an area of approximately 10 km 2 .…”

“…Much attention has been devoted to its conservation by the Chinese Government and numerous research institutes throughout the world; its geology, moisture source, climate, and ecology were studied (Guo et al, 2009;Li et al 2010a;Li et al, 2010b;Li et al, 2011). The surrounding environment has been strictly protected, which makes it difficult to find and study the underground characteristics of the sand wedge.…”

The international journal Landslides (ISSN 1612-510X), launched in 2004 and published by Springer Verlag, soon gained international recognition as the only specialized scientific journal in the world dedicated to different aspects of landslides, and as one of the leading world journals in the field of geological engineering. After 7 years, seven published volumes with 28 issues and 290 published papers on 2,794 pages, there is time to make a comparison with other related journals that also cover the field of landslide risk mitigation. The critical review of these seven publishing years was done using ISI Journal Citation Reports produced by Thomson Reuters, and available scientometric data from the ISI Web of Knowledge and SCOPUS. The data presented in this paper and the analysis shown may help the Editorial Board to further improve the journal into the direction of a high quality scientific journal with even higher impact on the international research community in the field of landslide risk mitigation.
