IMPROVEMENT OF BEARING CAPACITY OF SANDY SOIL BY GROUTING
The constructional activities in the coastal areas often demand deep foundations because of the poor engineering properties and the related problems arising from weak soil at shallow depths. The very low bearing capacity of the foundation bed causes shear failure and excessive settlements. Further, the high water table and limited depth of the top sandy layer in these areas restrict the depth of foundation thereby further reducing the safe bearing capacity. Grouting, which has several applications in the field of civil engineering, was once considered as a mysterious operation. The effectiveness of grouting requires a lot of understanding, skill, meticulous attention and an intuitive perception Grout is injected under pressure into the material to be grouted until it fills the desired volume of material around the hole or until the maximum specified pressure is attained and a specific minimum grout flow is reached. the strength improvement of loose sandy soils through cement grouting Permeation grouting is a simple method of ground improvisation technique which helps to stabilize the loose soil stratum. Permeation grouting is a process of filling the pores in the soil with the cement slurry and improves the engineering properties of the possible solutions to the foundation problems by improving the properties of soil at shallow depths by using sodium silicate. The shear strength parameters in the loose and medium dense state of the soil are investigated by plate load test on the grouted soil sample by determining the correlation between load and displacement on the grouted medium.
