JIAN Hong-yu. In-situ model tests of behaviour of grouting under tip of precast concrete short piles in sand and gravel layers[J]. 2004, 25(10期 刊出日).DOI:
In-situ tests of the behaviour of grouting under tip of precast concrete short piles in sand and gravel layer were performed and The test process was presented in details. The results of bearing capacity tests of short piles in sand and gravel before and after grouting show that the vertical ultimate carrying capacity of single grouted precast concrete short pile in sand and gravel layer can be enhanced very much.
