摘　　要：通过试验室相似模拟试验,研究了锚拉支架支护散体顶板时拉杆的横向受力状态,依据试验结果并借助弹性地基梁理论对拉杆的横向位移和受力状态等进行了分析,建立了基于绳索理论的拉杆模型,求解得到了拉杆的变形轨迹方程、拉杆的拉力(张力)。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.
