Theoretic Analysis of Inner Force of Shield Tunnel According to Elastic Hinge Model
Elastic hinge model is one kind of reasonable models to analysis shield tunnel. However, no formulas are valid to calculate inner force caused by load of water pressure and elastic reaction. Mechanical equations of two kinds of load are built and inner force formulas are deduced. Results calculated by homogeneous ring model are contrasted with those by elastic hinge model and conclusion is derived. The contrast shows that the results according to elastic hinge model are more reasonable.
