摘　　要：缅甸密松其培电源电站是伊洛瓦底江密松和其培水电站的施工电源电站。施工导流采用一次性拦断河床隧洞导流方式,围堰均采用黏土斜墙土石围堰。土石方施工包括大坝坝基及左、右岸边坡、坝址左岸危岩体的明挖等,高边坡开挖与支护施工为土石方明挖的重点。共开挖4条隧洞,采取合适的进洞开挖方案以确保洞口安全成型是隧洞开挖的重点。通过对施工工期和施工强度的分析,提出了总体施工方案。Misong Qipei Hydropower Station is constructed to provide power supply for the construction of Misong HPP and Qipei HPP on Ayeyarwady River.Tunnel construction diversion was adopted,so the river was completely closed by clay inclined wall earth-rock cofferdam.Earth-rock construction items involved open excavation of main dam foundation,left and right bank slopes,dangerous rock mass on left bank etc.,with emphasis put on high bank slope excavation and supporting.Four tunnels were excavated in total.The key of tunnel excavation is a proper excavation scheme to ensure safe formation of tunnel portal.Based on analysis of construction period and intensity,the general construction scheme was put forward.
