Feb 23, 2020 A landslide is any geologic process in which gravity causes rock, soil, artificial fill or a combination of the three to move down a slope. Several things can trigger landslides, including the slow weathering of rocks as well as soil erosion, earthquakes and volcanic activity.

Centrifuge Model Testing Of Loess Landslides Induced By

Apr 04, 2020 Excavation leads to unloading rebound and stress redistribution in the soil of a slope near the excavation face. The process of reequilibrium of the stress is followed by large deformation or even failure of the slope. In this study, the excavation-induced Yangya landslide

Humaninduced Landslide On A High Cut Slope A Case Of

Dec 25, 2012 In China, landslides due to excavation in various engineering activities are frequently reported on cut slopes. Unfortunately, current knowledge of these landslides is still incomplete in certain key areas Wang, 1998, Huang and Chan, 2004. Hence, presenting representative case study on cut slope failure is useful for response of emergency ...

Landslide A landslide or landslip is a geological phenomenon which includes a wide range of ground movements, such as rockfalls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Although the act

Landslide Control Program At The Panama Canal

the excavation of the original construction, the Canal widening, the straightening and deepening, the removal of landslides debris, and more recently, of the Canal Expansion. All these events have imposed new challenges in the surveillance process and demanded the use of new techniques for data

Landslide Mitigation Techniques Pile Buck Magazine

Jan 29, 2020 There are several construction methods to mitigate the risk of landslides. These include retaining walls, soil nailing, ground anchor walls, and the use of horizontal drains. Make landslide risk mitigation part of your projects planning phase. Work with a professional to identify the risks and appropriate mitigation techniques.

Study On The Process And Mechanism Of Slope Failure

Mar 06, 2019 Mining under an open pit slope results in the collapse and slide of the slope. In this paper, a combination of methods including Google Earth and field investigations is applied to investigate the process of eastern slope failure induced by underground mining in the Yanqianshan Iron Mine over five years. According to the observed ground deformation features, the geomorphic zone of the eastern ...

Most Landslides In India Are Caused By Human Activity

Oct 06, 2020 A recent example of human-induced damage creating a higher risk of landslides is the Char Dam Road construction process, which activated new potential landslide zones in Uttarakhand due to the damage the construction caused to the fragile Himalayan ecosystem.

Gismulticriteria Evaluation Using Ahp For Landslide

Apr 24, 2019 For example, new road excavations or further construction on the land susceptible to landslides may activate landslide occurrence, as well as the presence of temporary water rainfall. Moreover, this is the case for most of the landslides in our

Landslide Types And Processes Usgs

parts of a landslide. TYPES OF LANDSLIDES The term landslide describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a com-bination of these. The materials may move by falling, toppling, sliding, spreading, or flowing.

A Thrust Loadcaused Landslide Triggered By Excavation Of

Nov 14, 2014 After the excavation of the toe of the slope, the landslide stability factors reduced to less than 1.0, and the landslide was formed. If the percentage of increase in the stability factor is defined as an increment divided by the initial stability factor, then the percentage of increase in the stability factor of the lower sliding surface was ...

Landslide Process And Impacts A Proposed Classification

May 01, 2013 As noted before, landslide may be associated with denuding large tracks of forest and the destruction of vegetation cover of thousands of square kilometers which result in an accelerated erosion rate and larger landslides. This process is common in many parts of the world, particularly in tropical regions as a result of the intense ...

TYPES OF LANDSLIDES Landslides describe a wide variety of process that result in the downward and outward movement of slopes. Slope including the material like rock, soil etc. A. Slides the cracks. In landslides the more restrictive use of the term in mass

Landslide Stabilization Femagov

Dec 02, 1997 The subgrantee also submitted a consultants report that described 1 improvements that existed on the slope at the time of the landslide, 2 the threat to life, safety, and improved property from another slide, and 3 stabilization of the slope excavation at the toe of the slope and construction of an engineered-fill buttress.

What Causes Landslides To Occur Western Forestry

Anthropogenic i.e., excavation, etc. Some processes increase shear stresses. Others decrease shear strength. Generally, FS is defined as ratio of shear strength to ... Identify the process for which slope stability analysis is ... The exception is for existing landslides forensics. ...

3 Landslide Hazard And Risk Assessment

vulnerability assessment is a complex process that should consider multiple dimensions and aspects, including both physical and socioeconomic factors. Physical vulnerability of buildings and infrastructure is a function of the intensity of the landslide event and the resistance levels of the exposed elements.8910111213,,,,,
