Abstract

Abstract

Post-grouting technology can improve the disadvantage of bored piles. It has been proved that post-grouting technology can advance the bearing capacity and reduce the settlement of pile markedly by some post-grouting experimentation. Side frictional resistance distribution map of pile has been gained according to distributed optical fibre detection, and post-grouting effect and mechanism of action are also analysed.
