    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 slopeforming materials including rock, soil, artificial fill, or a combination of these The materials may move by falling, toppling, sliding, spreading, or flowing1 Introduction Human activity has been recognized as an important triggering factor that leads to many landslides (Turner and Schuster, 1996, Huang and Chan, 2004, Erginal et al, 2008, Ayalew et al, 2009)Humaninduced landslides usually occur on cut slopes due to excavation, which can cause many fatalities and strong destruction (Huang and Chan, 2004, Borgatti and Soldati, 2005,Humaninduced landslide on a high cut slope: a case ofDue to excavations and continuous rainfall, two landslides occurred on February 9, 2018, and July 28, 2019, respectively, in the quarry of the Changdifang Reservoir engineering area, in Yingjiang County, Yunnan Province, China The volume of the second landslide was approximately 24 × 105 m3, threatening the safety of construction workers and the hydropower station project constructionCharacteristics of failure area and failure mechanism of a

  • Study on the Safety Distance of a Tunnel UnderTraversing

    The experimental results show that a large area of plastic zone is formed in the process of tunnel excavation in a landslideprone slope, which seriously increases the possibility of potential landslides The distance between the tunnel vault and the sliding surface has a significant effect on the surrounding rock stress and strain Landslide Hazard Zonation Methods: A Critical Review Applying restrictive zoning codes for development or codes for excavation, construction, or grading, designed to reduce damages due to landslides, in areas not in the actual process of landslideLandslide Hazard Zonation Methods: A Critical ReviewThe landslide formed several months after excavation at the building site of the Medical School in Trstenik, Split is shown in Fig 2 Fortunately, the landslide occurred during the night, therefore the lives of workers at the bottom of the foundation pit were not endangered Download : Download fullsize image; Fig 2Impact of weathering on slope stability in soft rock mass
