| 摘 要： | 乌东德水电站右岸导流洞受因民组第2段薄层—极薄层大理岩化白云岩的影响,几乎贯穿了以导流洞上游洞段为代表的整个大型地下洞室群,在国内外大型地下洞室工程中实属罕见。施工过程中必须结合不良地质条件对开挖支护的影响,采取科学、合理的施工方法,并通过现场不断调整、优化方案,最终达到了快速、安全、优质、高效的完成工程建设目标。

| Abstract: | Affected by thin - extreme thin marble-like dolomite, Section 2, Yinmin Group, the diversion tunnel on right bank, Wudong- de Hydropower Project, is passed through almost by the dolomite the large-scaled underground caravan group with the upstream section of the diversion tunnel as representative. This is rare definitely in construction of large-scaled cavern group both in China and abroad. Therefore, scientific and reasonable construction methods shall be applied in combination with affects on excavation and support by the mffavorable geological conditions during construction. Furthermore, the construction goal of high speed, high quality, safety and high effi- ciency can be realized through continuous adjustment and optimization of the construction schemes. |
