Lightweight Underground Structures
The behaviour of simple thin-walled structures under soil cover and surface pressure has been examined by the author and others, using statically and dynamically loaded models. The results are summarized and used as a basis for presenting fundamental equations that might be usedfor initial design calculations. Particular reference is given to strength, stability and safety, and to the ways in which flexible substructures differ fundamentally from more conventional rigid forms.
