Effect of the Position of Geotextiles on the Strength Characteristics of Subgrade Soil in Bituminous Pavements
Abstract: In the past 20 years, many new road improvement techniques have revolved around the use of geosynthetics. Geosynthetics may be used in those areas where the soil remains saturated part of the year or over clay and moist silty weak subgrade soils. The quality and life of pavement is greatly affected by the type of subgrade, subbase and base course materials. Subgrade soil is the bottom most layer of the …

Settlement of Soil while Digging
Abstract: While digging of soft soil, collapse of soil takes place. When load of man is more than bearing strengthof soft soil, the soil will settle down. Hence bearing strength of mud soil is found at a particular depthand this is compared with load coming due to man. If weight of man is more as compared to bearingstrength of wet soil, the settlement will occur. The process of excavation in soft …

Experimental Investigation of Effect of Soil Structure Interaction on Buildings
Abstract: In the conventional analysis and design, buildings are generally considered to be fixed at their bases, but in actual practice, the support condition depends on the type of soil on which it is founded. The flexibility of the soil medium allows the movement of soil and foundation, which decreases in the overall stiffness of building frames and results in a subsequent increase in natural periods of the system. Thus, the …
