摘　　要：通过实验室相似模拟试验研究了锚拉支架支护散体顶板的支护机理,发现锚拉支架支护散体顶板时出现了两个拱,称之为第一拱、第二拱,继而依据试验结果并借助有关理论建立了简化的力学模型,对锚拉支架支护散体顶板的两个拱现象进行了深入的理论研究。The mechanism of the truss supporting loose roof is studied through physical simulation tests. Two arches named the first arch and the second arch are found in loose roof in simulation tests. The simplified mechanics model of the truss supporting loose roof is set up according to test results and in virtue of some theory. The two arches of truss supporting loose roof are studied thoroughly in theory. The deduced calculation formula provides calculation methods and theoretical references for parameters designs of truss supporting loose roof and is of important maturational meaning to practice.
