Abstract

Abstract

Based on a post-grouting engineering and comparisons of static loading tests (some is post-grouted and the other not). The author analyzed the laws of bearing capacity and settlement, then provided some beneficial references to similar engineering. Post-grouting can increase the bearing capacity of the side and bottom resistance, decreases the settlement of pile effectively. The grouting pressure is a changing value within certain limits, the maximum grouting pressure become greater as time changes. The piles are harder post-grouted and with more grouting pressure. The parameter of these piles should be en sured by field experiments.
