... ABSTRACT: Southern Thailand was subjected to an intense rainfall in November, 1988. This rainfall triggered thousands of slope failures in the Khao Luang Mountain Range and caused widespread flooding in southern Thailand. The landslides, debris flows and flooding caused the deaths of 370...

... ABSTRACT: The Geotechnical Engineering Office keeps comprehensive rainfall and landslide data. A GIS database of all sizeable man-made slopes and retaining walls in Hong Kong is also available. Apart from basic information on slope geometry (height and gradient), the database contains other...

... criteria (GEO, 1984). This would seem reasonable as under normal conditions, groundwater level is wholly governed, in some way, by antecedent rainfall. In adopting this approach, a first step must be to determine the rainfall duration period that influences a particular slope. This has been attempted...

... earth falls and shallow slips can occur during rainfall due to saturation and loss of strength with time. At steep benches (> 55o) exposing Zone II with day-lighting relict discontinuity planes, wedge failures can occur due to saturation and low shear strengths. During periods of intense...

... ABSTRACT: The behavior of seepage flow developed in an embankment due to rainfall and its associated features of expansion of the saturated wet zone, which promotes instability of slopes, are studied in this paper. Centrifuge seepage tests are conducted on sand model fills by use of a newly...

... Provinces of the State of Oregon, U.S.A. Abundant rainfall, between 90 to 165 cm per year, creates a soil profile typically composed of clayey silt residual soils with a relatively pervious relict structure, and a zone of highly plastic clay (CH) at depth overlying weathered bedrock. The depth...

...STUDY ON THE SLOPE STABILITY WITH MOISTURE DISTRIBUTION INFLUENCED BY VEGETATION AT SLOPE FACE Asako Togari-Ohta1, Tomoyasu Sugiyama2 and Hisashi Muraishi3 SUMMARY We performed a series of laboratory experiments using a large-scaled rainfall simulator and the stability analyses, in order to obtain...

...PERFORMANCE OF STABILIZED LARGE-EXCAVATED SLOPE Y.N. Lee1, D.Y. Kim2 and Y.H. Suh3 ABSTRACT After heavy rainfall at Kangchon-Ri in Korea on 27 July in 1996, an excavated and reinforced slope for condominium construction site was failed. To figure out the cause of the slope failure and to plan...

... ABSTRACT: In this study, the stability analysis of slope failure that occasionally occurs when rain falls was carried out. This paper focuses especially on the stability of large-scale cut slope exposed to heavy rainfalls. The study was carried out on a cut slope which is 52 meters high...

.... It was found that the inducement of landslide was started from the lower part of middle slope. The seepage from upper slope as well as back-up migration of saturation front in response to rainfall played an important role in triggering the slope failure. Indeed, the largest increment of pore water pressure...

...NUMERICAL SIMULATION FOR EVAPORATION AND INFILTRATION THROUGH UNSATURATED SOIL Ryosuke Kiamura1,Yuji Miyamoto2,Yu Shimizu3 ABSTRACT In the southern part of Kyushu Island, Japan, slope failures often occur due to heavy rainfalls in the rainy season (from June to September). Most of these slope...
