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).

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 ...
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 ...

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.
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.

Granite stone crusher manufacturer Xuanshi is a granite crusher manufacturer in China, and supplies all kinds of granite stone crushers, screen and grinding machines for granite quarry plant in USA, India, Vietnam, Qatar, South Africa, Germany, China, Congo, Ethiopia, Zimbabwe, Canada, Spain, Sweden, Finland, Portugal, Norway.
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 ...

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,
The land area of Hong Kong is 1101 km2 with a population of million. In Hong Kong''s geology, the main rock type is granite, approximately 90%. The weathering of the rock has resulted in completely decomposed granite (CDG) soil in the most land area. Therefore, the CDG is commonly encountered in most projects in Hong Kong,

The CDG soil is a common type of slope soils in Hong Kong. A pullout box apparatus is designed by the author in order to perform laboratory pullout tests, allowing a sealed condition for the pullout test of a grouted nail on a water submerged soil with a vertical stress up to 300kPa imposed on the testing soil.

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.
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.
