复杂地下工程施工安全风险评估与控制

Safety risk assessment and control for construction of complex underground engineering

为了解决地下工程施工中对已有建(构)筑物及管线的保护、不良地质问题的处理、开挖施工的安全,结合工程实例,分析工程施工环境中的安全风险源分布、评价及对结构施工的影响.借鉴北京地铁地下工程施工安全风险控制标准,提出了各种工况或不良工程地质条件下的施工工艺及安全控制措施.

In order to protect existing buildings and pipes in construction of underground engineering,deal with harmful geological problems and ensure the safety of excavation construction,this paper analyzes the distribution,evaluation and influence on structural construction of risk sources in construction environment combing project examples.Using risk control criterion of construction safety of Beijing metro underground engineering for reference,this paper puts forward construction technology and safety control measures in various operating conditions and harmful geological conditions.
