    基于AHP和未确知测度法隧道施工风险评估与控制

    RISK ASSESSMENT AND CONTROL OF TUNNELING BASED ON AHP AND UNASCERTAINED MEASURE METHOD

    • 摘要: 隧道施工风险一方面取决于地质条件、设计条件等客观因素的复杂性,另一方面也决定于施工技术水平、灾害体探测能力、监测控制能力这些主观因素,其实质是两者水平的比较。基于此,本文选取围岩条件、隧道设计条件、施工措施质量控制、地质预报能力、施工队伍素质和监控测量组织管理能力6个主要因素作为评价指标,采用层次分析法确定指标权重,依据未确知测度理论建立了隧道施工风险评价模型,对隧道施工风险进行定量评估。最后将本套评估系统应用到深圳东部过境高速公路连接线隧道施工,根据评价指标权重占比较大和风险评分较高的指标分析出隧道施工中的风险点,并有针对性地提出改进措施和施工建议,在现场整改的基础上,利用模型再次评估,直至风险达到可接受的程度为止。工程实践表明,该方法获得了理想的风险控制效果。

       

      Abstract: The risk factors of tunnel construction are not only the objective factors such as complex geological conditions, but also the subjective factors such as construction level. Therefore, this paper attempts to integrate subjective influencing factors into the evaluation index system. Six factors such as surrounding rock conditions, geological prediction ability and construction team quality are selected as the risk evaluation indexes of tunnel construction according to relevant codes and engineering examples. It takes shenzhen east transit expressway connecting line tunnel construction as an example and uses analytic hierarchy process to determine index weight. According to the unascertained measure method, we evaluated the construction risk level of the tunnel and analyzed the possible risk points, and put forward targeted improvement measures and construction suggestions. On the basis of on-site rectification, the model was used to re-evaluate until the risk is acceptable. Engineering practices showed that this method achieves ideal risk control effect.
