Abstract
The slurry wall bored grouting has some defects. The pile-base post grouting technique can effi- ciently make up these defects and greatly improve the bearing capacity. Based on the pile-base post grouting technique and its process analysis, this paper carries out a detailed analysis about the improvement of mechanism of bearing capacity and mechanism of spherical expansion by the use of pile-base post grouting technique, as well as the estimation method of the bearing capacity of pile-base post grouting pile, which has a certain refer- ence value for theoretical research and technical application of the technique.
