Softening of Fill Slopes due to Moisture Infiltration

Journal of Geotechnical Engineering, 1990
Fill in slope areas is generally placed and compacted near optimum moisture, which is often well below saturation. At optimum moisture content, compacted clayey fill has high shear-strength characteristics because of negative pore pressures. After construction of the slope, additional moisture is introduced into the fill by irrigation, rainfall, or ...

Fill Placement on Slopes Underlain by Franciscan Mélange

Journal of Geotechnical and Geoenvironmental Engineering, 2011
Distress in two housing developments was caused by a deep bedrock landslide triggered by placement of a large upslope fill. The large fill was placed to create a visual barrier between the upslope development and downslope housing developments and to balance the cut and fill quantities for the upslope site.

Experimental and numerical investigations of the behaviour of footing on geosynthetic reinforced fill slope under cyclic loading

Geotextiles and Geomembranes, 2018
This paper investigates the cyclic loading responses of a strip footing supported by a geosynthetic reinforced fill embankment. A series of large-scale model footing tests were conducted first to investigate the accumulation of permanent footing ...

Lateral Extension of Compacted-Fill Slopes in Expansive Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2015
AbstractMany compacted embankments are composed of expansive soils. Water from landscape irrigation, precipitation, and subsurface seepage can gradually infiltrate throughout the fill and cause bot...

Evaluation of landslide triggering mechanisms in model fill slopes

Landslides, 2004
Hong Kong is particularly susceptible to landslide risk due to the steep natural topography and prolonged periods of high intensity rainfall. Compounding the risk of slope failure is the existence of loose fill slopes which were constructed prior to the 1970’s by end-tipping.

Investigations of soil nails in loose fill slopes

2014
The prescriptive re-compaction method has been used as a common technique for upgrading loose fill slopes in Hong Kong. Due to the heavy plants required for the re-compaction work, the method may be extremely difficult and dangerous to be applied in many congested areas.

Instability caused by a seepage impediment in layered fill slopes

Canadian Geotechnical Journal, 2008
The underlying cause of loose fill slope failures in Hong Kong has been attributed to static liquefaction during heavy rainfall. A series of centrifuge model tests and numerical analyses were conducted to illustrate that instability of a fill slope inclined at approximately the internal friction angle of the soil can be triggered by confined ...
