摘要:随着国家城市化进程不断加快，地下结构的修建呈井喷式发展，根据地铁设计规范，区间隧道上下行线间需要设置联络通道。传统以矿山法开挖辅以冷冻、注浆加固的工法存在工期长、对周边环境影响大等缺点，为此开展BIM技术在创新工法-机械法联络通道中的应用研究。采用参数化模型进行工程结构设计模拟和集约化施工设备的优化设计，以BIM技术作为模型和信息的载体，根据现场施工和科学研究对模型进行反馈修正、深化设计，提取模型数据，结合其他技术，进行方案、现场、进度、成本管理等的应用。籍以安全高效地完成国内首座机械法联络通道的修建，提升了项目的综合管理水平，缩短了工期，保证了工程建设质量。为接下来的机械法联络通道的修建提供理论依据和技术支持，也为联络通道修建技术的发展指明方向。

Abstract: With the constant acceleration of the national urbanization process, the construction of underground structure is in a blowout development. According to the metro design specification, the connection channel needs to be set up for the upper and lower line of the interval tunnel. The traditional mining method combined with freezing and grouting reinforcement has disadvantages such as long construction period and great impact on the surrounding environment. Therefore, the application of BIM technology in the connection channel of innovative engineering method and mechanical method is carried out. The parametric model is adopted for the engineering structure design simulation and optimization design of intensive construction equipment, with the BIM model seen as a carrier of information. Based on site construction and scientific research, the model is modified by feedback and further design. Data in BIM model is extracted and, combining with other techniques, applied in the management on scheme, construction site, schedule and cost. In this way, the construction of the first mechanical communication channel in China is completed safely and efficiently, with improving management level on comprehensive projects, shortened construction period and good construction quality of the project. Meanwhile, it provides theoretical basis and technical support for the construction of the mechanical communication channel, and also points out the direction for the development of the construction technology of the communication channel.
