地铁盾构区间隧道施工风险的分析与控制

Analysis and Control of Construction Risk of Metro Shield Intersection Tunnel

从分析国内外地铁盾构施工研究资料入手,进而详述盾构施工法的原理及工艺特点.通过对其整体的施工流程及机理的剖析,对其中所存在的风险作了简要的分析与辨识.此外,通过对盾构施工风险产生的机理论证,给出了其风险评价模型.最后,针对地铁盾构施工时可能发生的常见风险给予了具体分析,并结合分析给出了合理的风险控制建议.

In this paper,starting with the analysis of domestic and foreign research data on metro shield construction,the principle and technological characteristics of the shield construction method are described in detail.Through the analysis of its overall construction process and mechanism,the existing risks are briefly analyzed and identified.In addition,the risk evaluation model is given by demonstrating the mechanism of shield construction risk.Finally,aiming at the common risks that may occur during the construction of metro shield construction,a concrete analysis is made and the reasonable risk control suggestions are given combined with the analysis.
