Study on the bearing capacity behavior of the excavated belled piles on the complicate old gully site

This article deals with a test carried out on the artificially excavated belled piles on a certain complicate old gully site by means of embedding earth pressure cells and reinforcement stress gauges. It also investigates the distinguishing characteristic of stress distribution on pile bottom plane and the effect of the main reinforcement of pile body and the hooped reinforcement on pile top, thus providing new practical information about the bearing capacity of excavated belled piles.
