摘　　要：随着我国基础设施的不断建设,隧洞混凝土施工越来越广泛,混凝土在基岩地下水的冲蚀下,发生对钢筋锈蚀、混凝土溶蚀,缩短隧洞寿命、降低使用年限。混凝土土浇筑后,大量地下水被归集,从施工缝部位渗出。隧洞固结灌浆能有效的固结岩体、阻断地下水,针对地下水位线下不良地质段固结施工技术分析总结。并进行工程经济效果评价。With the continuous construction of infrastructure in our country,the tunnel concrete construction is more and more extensive.Under the erosion of bedrock groundwater,the concrete corrodes the steel bar,dissolves the concrete,shortens the service life of the tunnel and reduces the service life.After the concrete soil is poured,a large amount of groundwater is collected and seeps out from the construction joint.Tunnel consolidation grouting can effectively consolidate the rock mass and block the groundwater.This paper analyzes and summarizes the consolidation construction technology for the unfavorable geological section under the groundwater level.And evaluate the economic effect of the project.
