The interface can be defined as the zone in which the transfer of stresses occurs between soil and structure. The behavior interface is significantly influenced by stress state variables. In this paper, the influence of matric suction and counterface roughness on the interface shearing behavior was examined by conducting a series of suction controlled direct shear test on the interface formed ...
Aug 28, 2008· Does 3035 deg refer to joint sliding, or to intact but decomposed rock treated as a continuum? I know nothing of Hong Kong geology, beyond that there is a lot of granite and decomposed granite, and landslide problems. By stress ratio, you are referring to sigma1/sigma3? If so, there seems to be a mismatch between K=4 and the strength ...
In this paper, the shearing behavior of completely decomposed granite soil and steel interfaces is examined using a modified suctioncontrolled direct shear apparatus. A series of direct shear tests was performed on two different types of soilsteel interfaces under different stress state variables.
In his 1893 book, "Our Island – A Naturalist''s Description of Hong Kong" (Figure 3) (at that time, Hong Kong consisted only of Hong Kong Island, a portion of the Kowloon Peninsula south of Boundary Street, and Stonecutter''s Island), Skertchly recognized that granite and volcanic rocks, including feldspathic quartz porphyry, formed ...

Completely decomposed granite (CDG) is abundant in Hong Kong. It has been used extensively as fill materials in various applications, such as backfilling materials for retaining structures and pavements.
HONG KONG (Reuters) — Hong Kong''s opposition camp set up polling booths across the Chineseruled city on Saturday for primary elections aimed at selecting democracy candidates who stand the best
overlie alluvium and completely decomposed granite. The rock along the Main Tunnel alignment is Shatin granite with occasional intrusions of fine to medium grained granite dykes and basalt dykes. The water table generally lies within 1 to 2 m of the existing ground level and the maximum hydrostatic pressure at the tunnel invert is around bar.
Completely Decomposed Granite (CDG) is one of the most typical soils found in Hong Kong. However, limited attention has been given on the effect of fines content on its engineering properties. A series of laboratory tests was conducted to examine the effect of fines content, varying from 0 20%, on the engineering properties of CDG.
The proposed SWSPS is located along Chung Kong Road, Sheung Wan, Hong Kong. The footprint area of the pumping station structures measured approximately 56m long and 43m wide, whereas the ground level is approximately +4mPD. The SWSPS is surrounded by various structures, which are sensitive to ground movement. To the north is a vertical seawall,
This was accompanied by the intrusion of granite magmas. The older rocks in Hong Kong were strongly deformed. From about 200 to 80 million years ago, a convergent margin tectonic setting developed along the southeastern coast of China. In the Hong Kong region, active volcanoes erupted ash and lava between about 165 and 140 million years ago.
Industrial clays, geosynthetics and grouting are proven solutions frequently used for similar applications. To provide a sustainable and lowcost solution to create an engineered water repellent soil, this study explored how Tung oil, a Chinese traditional vegetation oil, affected a Hong Kong completely decomposed granite (CDG).
To investigate the bond yield characteristics of undisturbed completely decomposed granite (CDG) which is widely distributed in Southern China, a series of conventional drained tests were conducted. From the test data, some insights are obtained as follows: for undisturbed CDG soils, the bond yield point during shearing could be identified on the curve of the normalized tangential stiffness ...

The distance between the normal compression line and critical state line is larger for the S/F specimens than for the D/MT specimens. For residual soils like Hong Kong completely decomposed granite, which contains a significant amount of fines, it therefore seems necessary to understand the potential differences caused by different preparation ...
