某地铁隧道的风险源分析及控制措施

Risk Source Analysis and Control Measures of a Subway Tunnel

风险工程是指项目建设中存在的安全风险,风险源等级的划分应根据工程特点、周边环境、影响程度等多种因素综合确定。地铁隧道的风险源主要包括工程自身风险和环境风险。本文针对某地铁隧道的自身风险和旁穿高架桥桩基础的环境风险进行风险识别和评估,通过技术、经济比较分析,制定了针对性和可操作的风险控制措施,有效的降低了施工过程中的风险概率,保证工程自身和周边环境的安全及正常使用。

Risk engineering means the safety risk existing in the construction of a project, the classification of risk sources should be based on the characteristics of the project, the surrounding environment and the degree of in- fluence.The risk source of subway tunnel mainly includes engineering risk and environment risk.Risk identifica- tion and evaluation of environmental risk of the subway tunnel and the risk of their own side wear of viaduct pile foundation.Through technical and economic comparison analysis,targeted and operational risk control measures have been formulated,effectively reduce the risk probability in the construction process,ensure the safety and normal use of the project itself and its surrounding environment.
