The formation of orthogonal joint systems and cuboidal blocks: New insights gained from flat-lying limestone beds in the region of Havre-Saint-Pierre (Quebec, Canada)

Autor: Shaocheng Ji, Yvéric Rousseau, Denis Marcotte, Noah John Phillips

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 15, Iss 12, Pp 3079-3093 (2023)

Vertical orthogonal joints are a common feature in shallow crustal rocks. There are several competing theories for their formation despite the ubiquity. We examined the exceptional exposures of orthogonal joints in flat-lying Ordovician limestone bed

Relationship between fracture spacing and bed thickness in sedimentary rocks: Approach by means of Michaelis–Menten equation

Autor: Shaocheng Ji

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 15, Iss 8, Pp 1924-1930 (2023)

Fractures occur in nearly all rocks at the Earth's surface and exert essential control on the mechanical strengths of rock masses and permeability. The fractures strongly impact the stability of geological or man-made structures and flow of water and

Genesis and exhumation of the Kongur-Muztaghata and Maeryang gneiss domes in NE Pamir since the Mesozoic

Autor: Zhiqin Xu, Bihai Zheng, Shaocheng Ji, Zhihui Cai, Hui Cao, Guangwei Li, Xijie Chen, Hua Xiang, Fenghua Liang

Publikováno v: Solid Earth Sciences, Vol 8, Iss 2, Pp 123-145 (2023)

The Kongur-Muztaghata-Maeryang terrane in NE Pamir is considered to be the western extension of the Songpan-Ganze terrane located in the northern Tibetan Plateau. The Kongur-Muztaghata gneiss dome (KMGD) is situated in the north while the Maeryang gn

A new interpretation for formation of orthogonal joints in quartz sandstone

Autor: Le Li, Shaocheng Ji

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 13, Iss 2, Pp 289-299 (2021)

Two vertical and orthogonal systematic joint sets are generally arrayed in a grid pattern on the bedding surface, which are the significant features of flat-lying sandstone terrains. Although extensive researches are reported on this topic, many fund

The relationship between diameter and depth of potholes eroded by running water

Autor: Shaocheng Ji, Le Li, Wei Zeng

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 10, Iss 5, Pp 818-831 (2018)

Geometrical analyses of 3930 potholes (3565 fluvial potholes, 237 marine potholes and 128 hillside potholes) from 33 localities in the world reveal a consistent, linear relationship: D = Nh + M, where h and D are, respectively, the depth and mean dia

Effects of porosity on seismic velocities, elastic moduli and Poisson's ratios of solid materials and rocks

Autor: Chengbo Yu, Shaocheng Ji, Qi Li

Publikováno v: Journal of Rock Mechanics and Geotechnical Engineering, Vol 8, Iss 1, Pp 35-49 (2016)

The generalized mixture rule (GMR) is used to provide a unified framework for describing Young's (E), shear (G) and bulk (K) moduli, Lame parameter (λ), and P- and S-wave velocities (Vp and Vs) as a function of porosity in various isotropic material
