.... In the present study, flume experiments were conducted. The effective stress was controlled by upward seepage to reproduce liquefied ground. As a result, it is found that scour profile is influenced by the effective stress, and backfilling of the scour hole due to slope failure is observed at low effective...

... Abstract Slope failure accounts for the majority of sediment disasters due to heavy rain. Both occurrence of seepage flow and pore water pressure in the infinitely long earth slopes are well known causes of slope failure. However, a slope failure could occur in case where the soils in slope...

... deformation. Artificial fill slopes suffered considerable collapse at four sites in the area surrounding the housing complex. This paper reports on the investigation of (1) the correlation between damage to houses and the ground conditions of the cut and fill area, and (2) the case of fill slope failure...

... identified as the predominated factors contributing to the slope failures at community on Kaohsiung slope land. Natural disasters damaging properties, infrastructure and human life can be serious all over Kaohsiung metropolitan area. To identify large scale soil mass movement, debris flow and surface runoff...

... Slope failures and landslides associated with earthquakes and typhoons are major natural hazards in Taiwan's mountain highways. This paper attempts to apply photogrammetry technique to carry out speedy in-situ survey. We firstly create the three-dimensional (3D) model of a brick wall...

... in the range of 2 degrees to 5 degrees. Calculations show the possibility of seafloor failures at Blake Ridge even for slope angles of 2 degrees depending on the thickness of the hydrate layer. This is consistent with reported seafloor slope failures at the Blake Ridge. A large geographical area with potential...

... ABSTRACT The major geotechnical problem manifested by Masado soils is shallow slope failures during intense precipitation. A light-weight dynamic cone penetrometer recently developed in France was used to investigate natural Masado slopes vulnerable to failure. A series of laboratory...

... in the future. INTRODUCTION Large scale landslide and soil mass movement have attracted the attention of human in the same way as other uncntrollable natual disaster, such as earthquake, volcanism, floods and debris flow, which threaten human lifes and their properties. Slope failures is usually related...

... ABSTRACT An approach using strength reduction factor (SRF) for finite element analysis with the provision of failure criterion and incorporation of graphical output to examine the failure zone developed was used in order to determine the slope failure and the corresponding safety factor. Slope...

... Group and its equivalents, Lushan Formation and Pilushan Formation. In the studied section, slopes failures were precisely located by means of GPS technology which were found mostly occurred at the northern aspect of slope with steepness within 30。-50。 and the U turns having large radius of curvature...

... ABSTRACT This study integrated the results of multibeam bathymetry data, side scan and subbottom acoustic data, and large-diameter piston coring to identify slope failures in water depths ranging from 850 m to 2800 m. A chronostratigraphy of the region was developed based on radiocarbon...

..., such as slope failure and mud volcanism. However, only a few gas hydrate bearing locations world-wide have been drilled and sampled. At all of these locations seep-related phenomena have been documented, including water-column gas and gas hydrate plumes, enhanced biological activity and/or the occurrence...

... during typhoon season. 7 faults and 3 synclines/anticlines were found in this region. The cleavages and joints were abundant in the geological formations. The slope failures mostly occurred between elevation 1600–1900m with slope aspect of south, southeast and southwest. Tsai (1996) indicated that slopes...

... the on- shore slopes of this small inclination seldom fail. it is possible that causes of submarine slope failure are of special nature that is not commonly seen on-shore. Volume of Failed Soil Mass Fig.4 shows the volume of failed soil It is found that a gigantic slope is possible to occur in the sea. it may...

..., improve resource management, a simplified analytical model that treats the failure mechanism as a sedimentation and slope oversteepening process and sediment motion as a propagating kinematic wave is developed. The model allows estimation of sedimentation rates necessary to initiate slope failures...
