摘　　要：东山供水工程9#输水隧洞进口段为土岩混合隧洞,为减小岩洞段爆破开挖对土石交界区及相邻土洞段的影响,保证施工及工程安全,施工中对土岩结合段采取文中的施工方法,有效地避免了地质灾害的发生,取得了较好的效果。The entrance section of the 9#water conveyance tunnel of Dongshan Water Supply Project is a soil-rock mixed tunnel.In order to reduce the impact of blasting excavation on the soil-rock joint section and adjacent soil cave sections,and ensure safety of construction and engineering,the construction method of this paper is adopted for the soilrock joint section during construction,which effectively avoids the occurrence of geological disasters and achieves good results.
