Develops theoretical principles for designing tunnels based on studies of strain energy, for engineers to use in conjunction with the design techniques that have been thoroughly learned over the years by practical experience. For example, once tunnels are dug, they are usually lined with concrete, but there is no theoretical basis for calculating t
