Analytical Determination of Capacity of Pile Using Base Grouting with a Case Study

Base grouting is used successfully worldwide for large diameter and long length piles. In India, extra dose bridges and cable stayed bridges are becoming popular presently. Therefore, long pile with large diameter is required for extra dose/cable stayed structures. Bottom cleaning is generally a common problem for long pile and it is found from pile load tests of long pile that actual pile capacity is lesser than that of design capacity with large settlement of pile due to insufficient bottom cleaning and presence of slurry mud and soft material from caving. Pile capacity improvement that could be derived from post grouting drilled shaft tips has resulted in a design methodology. This paper discusses the post grouting process and design procedure for the improvement of pile capacity. Correlations between applied grout pressure and end bearing improvement are presented, along with a case study with economics of using base grouting provision.
