R&D Knowledge Sharing Session on ‘Estimation of Ultimate Bearing Capacity of Soil for shallow foundation’ & ‘Innovative Method of Storm Water Management using Bioswales’

The Civil Engineering department had its third session under R&D cell on the 13^th february 2021 at 9.30 A.M. There were two speakers for this session.

Prof. Swaroopa Sail presented a research paper while Prof. Prachi Dessai presented on a recent trend.

Prof. Swaroopa presented her paper titled ‘Estimation of Ultimate Bearing Capacity of Soil for shallow foundation’.

Judging of ultimate bearing capacity is a tough process as it is hard to evaluate the shear strength parameters within the underlying soil structure. In her paper, to determine ultimate bearing capacity of soil for shallow foundation Terzaghi’s (1943) bearing capacity theory, Meyerhof’s (1963) bearing capacity theory, Hansen’s (1970) bearing capacity theories, Vesic’s bearing capacity theory and IS 6403: 1981 method, were used. It was also determined using SOFA and OptumG2 software. An equation was derived for finding ultimate bearing capacity using soil properties like density, specific gravity and grain size distribution using Regression Analysis. Paper related to present work was published in book chapter, Recent trends in Civil Engineering, Select proceedings of TMSF 2019.

Prof. Prachi presented on ‘Innovative Method of Storm Water Management using Bioswales’. She highlighted on the present flooding condition in Goa during monsoons and explained how bioswales could be used to tackle this issue. The participants were informed that bioswales were channels used to convey storm water run-off while removing debris. The advantage of these over normal dividers is that it avoids flooding due to accumulation of flood water. The bioswales are cost effective and easy to maintain.
