摘要
基坑工程为地下临时性工程,受很多不可预见因素的影响,基坑工程可能会超过设计使用年限。论文以某超期服役基坑工程为例,对现状基坑进行实地调查,对基坑结构的使用功能进行检测,并结合基坑变形监测对该超期服役基坑进行现状安全性评估,根据评估结果确定基坑工程是否需要加固处理。该工程实例研究可为超期服役基坑的现状安全性评估提供参考,对超期服役基坑工程的加固具有指导意义。
Foundation pit supporting project is an underground temporary engineering.Affected by many unforeseeable factors,foundation pit engineering may exceed the designed service life.In this paper,taking a foundation pit project in overdue service as an example,the field investigation of the current foundation pit is carried out,the function of the foundation pit structure is tested,and the status and safety of the foundation pit in overdue service are evaluated based on the deformation monitoring of the foundation pit,and whether the foundation pit project needs reinforcement is determined according to the evaluation results.The engineering example provides a reference for the current safety assessment of the foundation pit in extended service,and has a guiding significance for the reinforcement of the foundation pit in extended service.
