A review of pile-soil interactions in isolated, thermally-activated piles
Abstract
Abstract A number of full- and small-scale tests and numerical studies examining the behaviour of isolated thermal piles have now been published. The results have been collated and examined in terms of the pile head displacement and maximum stress changes observed during thermal loading. These parameters are complementary and are key design parameters. Taking full-scale tests as a benchmark, it is apparent that small-scale and numerical models are systematically biased towards low pile restraint. With some caveats, the limits defined by perfect restraint and free movement may be used in design to provide a first-order estimate of pile response.
