Urban underground interchange tunnel joint structure co-construction method
The invention belongs to the technical field of tunnel structures, and particularly relates to an urban underground interchange tunnel joint structure co-construction method. The method comprises thefollowing steps that S1, firstly, it is determined that an operable environment of structure co-construction need to meet the necessity, and the key point of structure co-construction is that a top plate of a lower-layer tunnel also serves as a bottom plate of an upper-layer tunnel; and S2, it is ensured that an elevation in longitudinal section design is limited. According to the urban underground interchange tunnel joint structure co-construction method, through combined application of accessories and a system, the tunnel structure co-construction method solves the problem of local conflictof upper-lower-layer tunnel structures to a certain extent, the implementation of an interchange scheme is facilitated, the excavation depth of a foundation pit is reduced, meanwhile, the soil-covering load of the top plate of the lower-layer tunnel is reduced, materials are saved, the stress of local joints can be determined through three-dimensional finite element calculation and analysis, a database system, an information system and an adjusting system are arranged, and the adjustable capacity of traffic flow is improved by means of traffic management.
本发明公开的属于隧道结构技术领域，具体为一种城市地下立交隧道节点结构共建方法，包括以下步骤：S1：首先确定结构共建的可操作环境，需达到其必要性，结构共建的重点是下层隧道的顶板兼作上层隧道的底板；S2：需要保证纵断面设计中标高受限，该种城市地下立交隧道节点结构共建方法，通过配件和系统的组合运用，隧道结构共建方法一定程度地解决了上下层隧道结构局部冲突的问题，便于立交方案的实施、减小了基坑开挖深度、同时减小了下层隧道顶板的覆土荷载，节省了材料，局部节点的受力可通过三维有限元计算分析确定，并设置数据库系统、信息系统和调节系统，借助交通管理提高对车流量的可调节能力。
