ASSESSMENT OF INFLUENCE OF BEARING CAPACITY OF SOIL BY GROUTING

Abstract

This project work is on assessment of influence of bearing capacity of soil by grouting. From the early days of simple slurry injection to current sophisticated techniques, grouting has played, and continues to play, an important role in remediation and new construction World Wide. As new grouting technology is developed, and existing technologies are refined, the range of applications increases. Soil improvement is carried out for various objectives to improve bearing capacity and reduce settlement of soft ground, control ground water, stabilize excavation bottom, prevent deformation of surrounding ground, clean up contaminated ground and avoid or minimize earthquake liquefaction – induced soil deformations and associated damage. Grouting is the most common technical method used for soil improvement and strengthening. The grout is based on cement, silicate, or other materials, selected to suit particular ground conditions and improvement objectives. The very low bearing capacity of the foundation bed because 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. This paper discusses grouting as one of the possible solutions to the foundation problems of coastal areas by improving the properties of soil at shallow depths. This project presents an experimental procedure for how to improve the bearing capacity of soil. The bearing capacity of sandy soil samples are improved with respect to w/c ratio 1:3, 1:6 respectively. The sample was collected and are subjected to various test. In relation to the subject matter, view of some scholars& authors were reviewed and data presented and analyzed. Conclusions are made at the end of this project Index Terms –– sieve analysis, specific gravity, proctor compaction test, grouting, direct shear test
