中文摘要:
      为保证盾构施工安全进行,基于熵度量法对盾构施工过程风险进行评价.根据沈阳地铁某盾构工程实际情况,提出包含盾构施工设备、工程水文地质、环境影响和盾构操作的4个一级指标以及22个二级指标的盾构施工风险评估体系,分析计算各指标的权重,建立基于熵度量法的盾构施工风险评价模型.通过分析可知,该地铁项目施工过程中的总体风险为可接受风险,需要引起重视.在规范的操作以及严密的监控措施下,可以做到施工过程中不发生危险.
英文摘要:
      In order to ensure the safety of shield construction, the risk assessment in shield construction was carried out based on entropy theory. According to the actual situation of the Shenyang Metro Line engineering, risk assessment system in shield construction was proposed,which contains 4 one-class indexes: shield construction equipment, engineering geological and hydro-geological, environmental impact and shield operation,and one-class indexes contained 22 two-class indexes, each index weight was analyzed, and shield construction risk assessment model was established based on the entropy theory. Through the analysis, the overall risk in the process is regarded as acceptable risk, need close attention. Based on regulate operation as well as strict control measures, there will be no risk in the construction process.
