A REVIEW ON LIQUEFACTION HAZARD ASSESSMENT FOR A REGION
Abhishek Kumar Tiwari, Dr. S.M. Ali Jawaid, Deepti Singh, & Tarik Salman
ABSTRACT- Earthquake is most dangerous natural disaster because of is unpredictable nature. And liquefaction is one of seismic event where soil can fail with devasting effect such as land sliding, lateral spreading or large ground displacement. The phenomenon of liquefaction has been seen after Nigata (1964) and Alaska (1964) earthquake. Earthquake reduces the strength and stiffness of soil by shaking and other rapid loading.Liquefaction is one of the most interesting but complex.....>> Read More
LIQUEFACTION HAZARD ASSESSMENT OF RAMGARH TAL PARIYOJNA
Abhishek Kumar Tiwari & Dr. S.M. Ali Jawaid
ABSTRACT- Determination of liquefaction potential due to earthquake is complex geotechnical problem. Many factors including soil parameters and seismic characteristics influence this phenomenon. The devastating damage of liquefaction induced ground failures in the Alaska 1964 and Niigata 1964 earthquakes serve as a clear reminder of such events. Liquefaction is one of the ground failures in potential earth science hazard. Since Gorakhpur falls in the area with high seismic probability.....>> Read More
GEO-FIBER REINFORCED FLYASH FOR GROUND IMPROVEMENT
Ravi Mishra & Dr. S.M. Ali Jawaid
ABSTRACT- This paper illustrates the possibility of utilization of the fly ash generated from the coal/lignite based thermal power plants through ground improvement technique, leading to an effective waste management. In this study samples were prepared by mixing different percentage of fly ash with different percentage of soil, with an aim to compare strength gain with geo-fiber. Fly-ash mixed with highly compressible soil and reinforced with geo-fiber may find potential applications .....>> Read More
PARAMETRIC STUDY OF A RETAINING WALL UNDER STATIC & SEISMIC LOADING
Abhay Tripathi & Dr. S.M. Ali Jawaid
ABSTRACT- This paper presents a parametric study on a retaining wall by different methods of analysis. The effect of internal friction angle, soil wall friction angle, wall inclination and seismic coefficient is shown graphically as well as in tabular form and a comparison of active and passive earth coefficients is presented for different methods. As the soil-structure interaction during the earthquake is very complex, Comparison of the various methods of analysis of retaining walls.....>> Read More
COMPARITIVE STUDY OF THE PROPERTIES OF FLY ASH CLAY BRICKS AND CLAY BRICKS
Ramji Porwal
ABSTRACT- Brick is one of the most widely used construction materials throughout the world since ancient time. Fly ash clay bricks are one of the best alternatives to the conventional burnt clay bricks. This dissertation gives the results of an experimental investigation in which the compressive strength, water absorption, density and durability of Fly ash-clay bricks are investigated by using varying quantities of fly ash with partial replacement of clay. The properties of Fly ash clay......>> Read More
