摘要
随着市政地铁工程规模的不断扩大,确保明挖车站施工的安全性与效率变得尤为关键。为更加科学地建设城市地下空间,保障地铁明挖车站的施工质量及效率,对放坡开挖法、围护结构加支撑法和悬臂式围护开挖法这三种技术展开了深入研究。放坡开挖法减少了对周边环境的干扰但需要更大的开挖面积;围护结构加支撑法能为复杂土层或建筑物密集地区提供稳定性;悬臂式围护开挖法则适用于土层坚硬或开挖深度较小的场合。通过对这些方法的综合分析,明确明挖车站的施工流程和关键技术点。研究得出结论:根据实际工程条件选择合适的施工方法是确保施工安全性和效率的关键。
With the continuous expansion of municipal subway projects,ensuring the safety and efficiency of open cut station construction has become particularly crucial.In order to construct urban underground space more scientifically and ensure the construction quality and efficiency of subway open cut stations,in-depth research has been conducted on three technologies:slope excavation method,enclosure structure support method,and cantilever excavation method.The slope excavation method reduces interference with the surrounding environment but requires a larger excavation area;The enclosure structure with support method can provide stability for complex soil layers or densely populated areas of buildings;The cantilever excavation method is suitable for situations where the soil layer is hard or the excavation depth is small.Through a comprehensive analysis of these methods,clarify the construction process and key technical points of the open cut station.The research concludes that selecting appropriate construction methods based on actual engineering conditions is the key to ensuring construction safety and efficiency.
