摘要
对场地狭小、基坑面积占比大、开挖深度深、周边环境保护要求高的深基坑钢筋混凝土栈桥的施工技术进行了研究。结合场内外交通条件,通过优化栈桥平面布置及其与首道支撑的相对位置关系,并采用施工设施集成化设计方式,在确保基坑安全的前提下达到了节约工期及成本的目标。
The construction technology of reinforced concrete trestle bridge in deep foundation pit with narrow site,large proportion of foundation pit area,deep excavation depth and high requirement of surrounding environmental protection is studied.Combining with the traffic conditions inside and outside the site,the trestle plan arrangement and its relative position relationship with the first support are optimized,and the integrated design of construction facilities is adopted to achieve the goal of saving construction time and cost while ensuring the safety of the foundation pit.
