“…(1) The intersection of the road cuts' trends with the trends of the bedding planes and two sets of joint planes (Table 1, and Figures 4-8 and 10), (2) the presence of active erosion areas surrounding the landslide areas (Figure 4), and (3) the oscillation of the water level in Dukan reservoir has formed unstable slopes along the lowermost parts of the already existing landslides ( Figure 12) and these in turn will effect on the toe area of the concerned slides. Such cases are well known and presented by many researchers, among them are Schuster (2006), Singh et al (2012), and Kaczmarek et al (2015). In Landslide No.…”

A B S T R A C TFour landslides of different sizes had occurred in 2012 along the main paved road between Dukan and Surdash. The landslides are within the Kometan Formation, which consists mainly of well-bedded and jointed marly limestone. The landslides are located in a narrow syncline trending NW-SE in between Khalikan and Kalo anticlines. The main reason of the landslides is the haphazard road cuts during the road construction and widening of the road latter on. Another reason that had accelerated the landslide is the fluctuation of water level in Dukan reservoir. The water level reaches the downslope area of the landslides. Satellite imagery was used to study the parameters of the landslides and have performed a fieldwork to confirm the acquired parameters and deduced other indications of the landslides, besides checking their stability. Landslide possibility study was performed using landslide possibility index at each landslide area and has found that the whole area is unstable showing high possibility of refailure. Stereographic presentation for the three landslides was used to show the relationship between bedding and joint planes and the road cuts trends. It was concluded that, in next rainy season, the whole area may form a severe geological hazard if necessary precautions are not considered. Therefore, urgent precautions were recommended to keep the slopes alongside the road cut as stable as possible.

“…A rise of this magnitude is unprecedented. The failure was probably triggered by the direct reduction in normal load within the toe of the slope and dynamic hydraulic pressure of underground water caused by the rising water level (Wang et al 2004, Singh et al 2012. Fig.…”

Background: The Shanshucao landslide is a bedding landslide in the Three Gorges Reservoir. This landslide had not been subject to obvious deformation in the past, nor had it been included in the list of geologic hazards previously identified in the Three Gorges Reservoir. Findings: The Shanshucao slope failed at 13:19 p.m. on Sep. 2, 2014, during which the northern soil mass slid rotationally on a plane under traction produced by the rocky bedding landslide to the south. The Daling Hydropower Station was situated on the Shanshucao landslide, and power generation pipelines feeding the station began leaking four hours before the incident. Heavy rainfall, fluctuation of water level in the reservoir, and leakage of tunnel pipelines caused a sharp increase of hydraulic uplift pressure within the slope. This was the key trigger of the incident.

“…The landslide incidence is frequent phenomenon in the tectonically and seismically active areas (Bolt et al, 1975). The rocks present in the reservoir area of the Baglihar dam site are fragile and lie within the Panjal Thrust Zone (Singh, 2012). The study area falls in the zone between Murree Thrust in the south and Panjal Thrust in the north.…”

The present study assesses the slope stability at the most significant Baglihar Dam for slope failure and landslides occurrences. The study comprises of twelve sites which were selected for detailed geotechnical investigation for assessment of potential slope failures using basic Rock Mass Rating (RMRb), Slope Mass Rating (SMR) and kinematic analysis techniques. The results show that even though the rocks are of fair quality but other factors including joint pattern and density caused by tectonic and anthropogenic activities have rendered three sites completely unstable, 8 sites are unstable and one site is stable. Moreover Nine sites are susceptible to wedge failure, six to topple and two to plane failure. The RMRb value varies from 45 to 55 and SMR value varies from 11 to 44. The thorough results and interpretation of work done is presented in this paper.
