Abstract:
Construction of the foundation on the marine the soil deposit is susceptible to excessive settlement and the construction of foundation is difficult. Although, the most common practice is to construct the raft foundation in these regions even for the low-rise building, excessive settlement can be observed in several building. So, in the present study, laboratory investigations have been done on the marine soil by modifying it with two different type of biopolymer such as Guar gum and Xanthan gum. The geotechnical properties of the soil modified with 1% and 1.5% biopolymer has been evaluated and the obtained properties has been used for settlement analysis. During the settlement analysis, the foundation soil model has been created as layered soil because the top layer has been replaced by biomodified soil. Several combi-nations have been created by varying the thickness of modified soil layer and the type and percentage of modifying agent. The settlement analysis has been performed in the settle 3D software and the biopolymer modification of soil has been found effective in controlling the foundation settlement.
