Underground energy storage is an important function of all supply systems, and especially concerning the seemingly eternal imbalance between production demand. Salt rock underground storage, for one, widely applied in both traditional renewable fields; this particular technique can be used to store natural gas, hydrogen, compressed air. However, resource diversification structural complexity ma...

A low-clearance tunnel portal in the shallow-buried, joint-developed, broken, and loose surrounding rock slope deposit may cause safety issues during construction. In this study, Guanyin Mountain Tunnel of Chong-Ai expressway was taken as a case characteristics broken rocks, their low clearance, shallow buried bias were comprehensively studied. The three-dimensional numerical model section cons...

The Nandongzi landslide occurred in the Yanshan region of North China. From 2017, slope has been significantly deformed after several excavations. Field investigations show that is a special toppling deposit does not have basic conditions. deformation mechanism become difficult issue for engineers, attracting attention scientists. Joint, surface, and borehole lithology surveys revealed surface ...

In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results  in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, doub...

Failures of road embankments on discontinuous permafrost commonly occur during thawing of the foundation soil. As an approximation, weak zones created by thawing of discontinuous permafrost can be considered as ‘voids’ within the foundation. Geosynthetic reinforcements have been used to bridge these ‘voids’ and provide support to the embankment fill. This paper presents results of a numerical i...
