摘要
已开挖的地下深基坑一旦停工搁置,本就具有一定风险性的基坑支护作为临时性结构,将进入更高风险的超期使用状态。应当采取诸如提高安全系数做设计复核、实施切实有效的工程措施、有针对性地动态监测以及建立周全的事故应急预案等手段,从而保证基坑支护体系在延长使用期内的可靠安全。
Once the excavation progress of the underground deep foundation pit is suspended,the foundation pit support,which has a certain risk,will get to higher-risk overdue use state as a temporary structure.Measures such as increasing safety factor for design review,implementing practical and effective engineering measures,targeted dynamic monitoring system and establishing comprehensive accident emergency plan should be taken to ensure the reliability and safety of the foundation pit support system in the extended servicing period.
