16 Oct how to prevent landslides in hilly areas
This can be achieved by arranging the longitudinal axis of the building parallel to the contour lines of the original topography, in which the building is underlain by fill of uniform thickness and therefore less differential settlement. The presence of subsurface water in an area may lead to the formation of cavities therefore inviting landslides.
Sandwich panels (amalgamation of two fiber reinforced cement sheets). Leafing through the history of an area and assessing how it behaves in different climatic conditions could prove to be very useful and help prevent landslides.
Updated Aug 07, 2020 | 00:07 IST With the three deaths due to incidents of drowning, landslides and tree falls since Tuesday night, the toll since the onset of the 4-month long South-West monsoon has begun has reached 30, official data said. They have provided expert advice on practical civil enginnering and have provided real insight on how to proceed as an organization. Water from heavy rainfall and Excessive waterare the frequent cause for landslides which weakens the slope materials.Other factors that weaken slope materials also contribute to the occurrence of landslides. It helps confirm the information acquired from the topographical data and also to obtain additional information from the site. It involves detailed study of geological maps so that the engineers are aware and understand the geological formation of the site of the proposed development. They are a fruitful source of all Civil Engineering information available. next: ".tes-slider-next265", jQuery(document).ready( function($) { }); An elderly woman trying to cross … For man-made slopes, there are many factors that can contribute to slope failures: Therefore, for the design of the slopes, proper information on soil properties, groundwater regime, geology of the site, selection of methodology for analysis are important factors that require attention from the Engineer. The discussion intensifies every time after an incident of landslide is raised up by media. In addition, the ground water profile should also be assessed. The factors that weaken slope materials also contribute to the occurrence of landslides include both natural events such as geological weathering and erosion and human-related activities such as deforestation and changes made to the flow of groundwater while slope is also most common factor. As you might expect, any hilly or mountainous area that receives frequent rain or snow is a prime location for a landslide. Heavy Rainfall: When sloped areas become completely saturated by heavy rainfall many times landslides can occur.
If possible, try to avoid using retaining walls as this will be costlier than normal earthwork solution. Earthquake- Seismic activities have always been a main cause of landslides throughout the world.
They are a pleasure to work with. When using piles to support buildings on fill, the design engineer should evaluate negative skin friction (down drag) acting on the piles if the ground is going to settle with time. Building construction in hilly regions requires comprehensive planning, site selection and design for slopes and sustainable concrete construction practices. Field mapping identified 548 landslides and most of them occurred during Summer 2017. Kerala: Heavy rains pound the state with landslides reported in hilly areas. Vivek Karindalam . fx: "fade", Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil. When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides. Water from heavy rainfall and Excessive waterare the frequent cause for landslides which weakens the slope materials.Other factors that weaken slope materials also contribute to the occurrence of landslides.

Sustainable development is the continued ability of a society, an ecosystem, or any such interactive system to function without exhausting key resources and without adversely affecting the environment. Green Building Materials for Hilly region: Sustainable development underscores the importance of taking a longer-term perspective about the consequences of today’s activities and of global co-operation among countries to reach viable solutions. In total, the inventory includes 730 landslides for Chittagong Hilly Areas from 2001 to 2017. Keeping the Safety-knots of building intact on hill-site is essential and often a topic of discussions among engineers and public. }); “I am grateful for the hard work and exemplary service provided by Concrete Civil and team. It is also very important to orientate the building layout to minimize potential differential settlement especially if the buildings are on filled ground.
Buildings or Structures with Heavy Loading. Any time plate tectonics move the soil that covers them moves with it. Itis a most attention taking natural disaster which mostly existed in hilly areas but recently increased in frequency in certain areas because of human activity. Thus it is very important to identify the aforementioned areas before beginning any kind of construction on a hilly area. The knowhow of the site-histories particularly previous landslides and underground services is very important for the planning of the layouts and designs.
Construction technique should be developed with locally available, easily workable materials which are mostly environmental friendly (like timber, stone mud and bamboo) and have good climatic resistance and have little or negligible impact on environment of hill settlement. Without the aid of mechanical root support the soil simply runs off when it contains too much water. In addition to causing extensive erosion and sediment yield in these regions, large landslides have been responsible for the creation of many lakes in the Alps and other mountain …
