Stress Field Analysis of Homogeneous Roof by Truss Support Based on Elasticity Mechanics Solution

摘要

This paper takes the solution of Boussinesq model, Cerruti model and Mindlin model as basic solution of elasticity mechanics. On the basis of research conclusion of the accuracy property of rock bolt stress field studied in reference, satisfictory elasticity mechanics solution of homogeneous roof rock stress field is given and the rule of stress field change with various parameters is studied.
