摘　　要：国内外城市地铁隧道建设呈现长距离化、地质条件多样化、施工环境复杂化等发展趋势,现有机械化施工方法对于工程的适应性受到了极大的挑战。多模式盾构/TBM掘进设备在复杂环境中具备良好适应性,在降低施工风险的同时提升掘进效率,可用于解决复合地层掘进设备选型难题。对不同类型多模式掘进设备的适应地层及工作特点进行了论述;基于国内外采用多模式掘进设备的典型工程案例,通过关键地层参数的统计分析,提出了多模式掘进设备选型原则及方法;综合考虑地质条件、工期、造价、环境影响等因素,分别建立了盾构、TBM模式适应度综合评价模型,并结合工期和造价确定模式转换下限长度进而对区段模式进行修正;最后以深圳地铁14号线区间隧道为算例,研究结果验证了多模式掘进设备选取方法的合理性。研究成果可为多模式掘进设备在我国隧道建设中的推广应用和适应性评价提供参考。Urban subway tunnel construction at home and abroad has shown different development trends,such as long distance,diversified geological conditions and complex construction environment,posing great challenges to the adaptability of existing mechanized construction methods.Multi-mode shield/TBM tunnelling equipment has good adaptability in complex environments,making it useful to solve the challenges in selecting the tunnellling equipment for composite stratum by reducing the construction risks while improving the tunnelling efficiency.This paper is a discussion of the adaptation of different types of multi-modal tunnelling equipment to different strata and working characteristics.Also,this paper proposes the principles and methods for the selection of multi-mode tunnelling equipment through statistical analysis of key stratigraphic parameters based on typical engineering cases at home and abroad where multi-mode tunnelling equipment is used.Furthermore,paying comprehensive consideration to the geological conditions,duration,cost and environmental impact,this paper constructs a comprehensive evaluation model of shield and TBM mode adaptability respectively,and determines the lower limit length of mode conversion with consideration to the duration and cost,before making modification of the interval mode.Finally,using the running tunnel of Shenzhen Metro Line 14 as an example,the research results verify the reasonableness of the multimode tunnelling equipment selection method.The research results can provide references for the promotion and application of multi-mode tunnelling equipment in China′s tunnel engineering and adaptability evaluation.
