Pile plate type ear wall type open cut tunnel structure
The invention discloses a pile plate type ear wall type open cut tunnel structure. The pile plate type ear wall type open cut tunnel structure aims to effectively improve the integrity of an open cuttunnel structure, reduce the risk of differential settlement and reduce the size and the dead weight of an ear wall structure, so that the construction cost is saved. The pile plate type ear wall typeopen cut tunnel structure is characterized in that each ear wall column is divided into a lower ear wall column section and an upper ear wall column section, bottom plates for transversely connectingeach ear wall column into a whole are arranged at the lower ends of the lower ear wall column sections, cross beams for transversely connecting each ear wall column into a whole are arranged at the lower ends of the upper ear wall column sections, and the bottom plates, the cross beams and each ear wall column form a reinforced concrete frame structure; precast concrete slabs are arranged at thesoil retaining side of each upper ear wall column in the upper space of the ear wall structure above the cross beams to form a pile plate wall structure used for bearing lateral backfill soil pressure; and in the lower space of the ear wall structure from the cross beams to the bottom plates, the lower ear wall columns and the side wall section of a lining structure are fixedly connected into a whole to form a pile plate wall structure used for bearing acting force such as lateral soil pressure, structural dead weight, and seismic force of the open cut tunnel structure.
一种桩板式的耳墙式明洞结构，以有效提高明洞结构的整体性和降低不均匀沉降风险，降低耳墙结构体积及自重，从而节省建造成本。耳墙柱分为下部耳墙柱、上部耳墙柱两段，在下部耳墙柱的下端设置将各耳墙柱横向连接为一体的底板，在上部耳墙柱的下端设置将各耳墙柱横向连接为一体的横梁，底板、横梁和各耳墙柱形成钢筋混凝土框架结构。在横梁以上的耳墙结构上部空间内，于各上部耳墙柱的挡土侧设置预制混凝土板，形成用于承受侧向回填土压力的桩板墙结构；在横梁至底板的耳墙结构下部空间内，下部耳墙柱与衬砌结构的边墙段固结为一体形成桩板墙结构，用于承担明洞结构的侧向土压力、结构自重及地震力等作用力。
