In this paper, the compaction grouting technology which is used to enhance
the bearing capability of cast-in-place piles in a loess region is experimentally studied
based on a static test in which some detectors are attached in situ along the test pile.
Some problems of the applications of the grouting method in the loess region are also
discussed. The bearing capability properties of the cast-in-place pile of a pile tip
compaction grouting are analyzed, so as to provide references for the application of the
technology in loess regions. Meanwhile, the bearing capability of the cast-in-situ pile is
compared with that of piles cast according to codes.
