Abstract

Abstract

The construction equipment and technology of tight confined pile are introduced. It is pointed that the increase in bearing capacity of the pile results from the densification of the soil under point of pile and around pile shaft. The results of load test of pile in two sites have shown that the tight confined pile has great potential in engineering application.
- tight confined pile,
- cone with wing,
- densification of soil,
- prestress,
- bearing capacity of foundation pile
