摘要
该文以节理岩体中水中隧洞为研究对象 ,考虑岩体结构面与洞室布置的组合 ,推导出超挖块体体积计算的一般公式。通过某水工隧洞的勘探平洞PD6的洞顶超挖块体的调查 ,评价了超挖块体体积及其分布 。
Taking the hydraulic engineering tunnel in jointed rockmass as an object of study, considering the combination of rockmass structural plane with the cavern arrangement, the paper derives the general formula for the over-excavation block volume calculation By the examination of the cavern top over-excavation block volume calculation for the exploration adit PD6 of a hydraulic engineering tunnel, it assesses the over-excavation block volume and its distribution Thus, it presents a certain basis for the excavation and solidification treatment of that horizontal tunnel
