摘　　要：提出了软岩巷道强壳体支护的基本内涵及3种基本支护形式,对锚杆强壳体支护原理进行了力学分析。在此基础上推导出强壳体合理锚杆支护长度、支护间排距、锚杆直径等支护参数的求算公式及其对强壳体结构的影响。研究结果表明,软岩巷道应用“短、细、密”锚杆支护效果优于普通锚杆支护,研究结果在龙口矿务局软岩巷道支护的实践中得到证实。Connotation and three kinds of basic support form of strong shell-body support in soft rock roadway is put forward in this paper. The support principle is analyzed by dynamics method,on the basis of which,calculation formula of reasonable bolt length,interval and diameter of bolt and its impact on support structure is educed. The result indicates that effect of 搒hort,thin and dense?bolt support precedes that of general bolt. The presented study result is approved in soft rock roadway support practice in Longkou mine bureau.
