RESEARCH ON LATERAL PRESSURE IN TRUSS ROD FOR SUPPORT OF LOOSE ROOF
锚拉支架支护散体顶板时拉杆的横向受力研究

The lateral pressure acting on rod is studied through physical simulation tests in the condition of loosed roof supported by truss rod. The lateral displacement and pressure of rod are analyzed according to test results and elastic foundation beam theory. The rod model is built based on rope theory. The deformation trajectory equation and tensile force of rod are obtained.
