Earthquake countermeasures in sloping land

WebFeb 12, 2024 · Structures resting on sloping ground are highly vulnerable to earthquakes due to irregularities in plan and elevation. Structures are often analysed under earthquake loadings, without considering the effect of soil–structure interaction (SSI). This practice is not advisable from practical point of view. In this present study, an attempt has been made to … WebJan 1, 2011 · Practical Countermeasures Reforestation and Green Belt Construction Cropping on hillsides is a main factor that exacerbates soil erosion and land degradation.

WebA landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. Presently, the majority of slope stability analyses evaluate a safety factor using a 2D representation of the slope, while 3D analyses of slope stability are much less reported44,45. It can be explained in part by the fact that a 3D model is likely to introduce a much larger number of degrees-of-freedom, which … See more In this paper, we first use reliability theory to back analyse the shearing strength parameters. Back analysis is an effective method for determining landslide parameters. For landslide mitigation work, the safety factor Fs is … See more Compared with the traditional LA method, the finite element method (FEM) performs better with the advantage of considering much complex boundary conditions, as well as the non-homogeneity of the soil and rock mass. … See more ipbes summary https://lomacotordental.com
