Journal ArticleDOI
Seepage Characteristics in Loess Strata Subjected to Single Point Water Supply
TL;DR: In this paper , a Conical-like cavity was formed near the water source, and the preferential passage of water flow appeared below the cavity, where a two-dimensional seepage diffusion calculation model was established and preliminarily verified by example calculations.
Journal ArticleDOI
Failure analysis and deformation mechanism of segmented utility tunnels crossing ground fissure zones with different intersection angles
TL;DR: In this article , a 3D-FDM calculation model of different intersection relationships between the segmented utility tunnel and the ground fissures using Flac 3D software is established.
Journal ArticleDOI
Large Deformation Characteristics and Treatment Effect for Deep Bias Tunnel in Broken Phyllite:A Case Study
TL;DR: Wu et al. as mentioned in this paper studied the support structure failure behavior and surrounding rock deformation mechanism with Wuduxi Tunnel as an engineering case and proposed double primary support-secondary lining to control the large deformation of surrounding rock.
Journal ArticleDOI

Face stability analysis of shallow circular tunnels in cohesive–frictional soils
TL;DR: In this article, a new 3D failure mechanism was proposed using the kinematic approach of limit analysis theory to determine the limit support pressure of the tunnel face, which was composed of four truncated cones on which a distributed force acts.
Journal ArticleDOI
Heavy rainfall triggered loess–mudstone landslide and subsequent debris flow in Tianshui, China
TL;DR: Wang et al. as discussed by the authors studied the formation and moving characteristics of the landslide and subsequent debris flow in the southern Dagou Village of Mapaoquan Town, Tianshui City, Gansu Province of China on July 21, 2013.
Journal ArticleDOI
