超大矩形断面浅覆土盾构顶管施工风险识别及风险评估
Construction risk identification and risk assessment of large rectangular shallow embedded shield pipe jacking tunnel
摘要
Abstract
The sources of risk of shield pipe jacking construction include the risk of equipment, the risk of tunnel entrance and exit construction, the risk of driving tunnel face and the risk of surrounding environment with regard to the super large cross-section, ultra-small spacing, porous rectangular shallow covering shield pipe jacking construction. Using the method ofR=P×C grading and fuzzy comprehensive evaluation, ranking and evaluating the source of risk, know that the risk level of equipment risk, the risk of tunnel entrance and exit construction, the risk of driving tunnel face is high and the risk of environment is moderate. And to take appropriate control measures, and the corresponding evaluation on the level of residual risk, combined the risk analysis with reasonable countermeasures, the measures was proposed to prevent or reduce the risk. The results of the study provide a scientific, systematic, comprehensive and practical basis for the decision of the engineering construction units and related departments to achieve security, economic and efficient management objectives.关键词
