随着城市地下空间的发展,变电站的建设也逐渐由传统的地面变电站转为地下变电站,它很好地解决了城市征地困难、环境要求严格等问题,然而地下变电站施工不可避免地与原有周围建(构)筑物相互影响。依托上海某110kV地下变电站深基坑工程,通过数值计算分析研究了该超深变电站基坑施工对紧邻供能管沟的影响,并在围护体系各项安全系数均满足规范要求而周边环境超出控制指标的情况下,提出了可行的土体加固方案,有效地控制因变电站基坑施工对周围环境的影响。对此复杂环境下变电站基坑工程施工的可行性做出评估,并优化设计方案,保证施工安全。
With the development of urban underground space, the construction of substation is also gradually transformed from traditional ground substation to underground substation. It solves the problems of urban land acquisition and environmental requirements. However, the construction of underground substation inevitably conflicts with the original surroundings Building (structure) building interaction. Relying on a deep foundation pit project of a 110kV underground substation in Shanghai, the influence of the construction of the foundation pit of this ultra-deep substation on the adjacent energy supply trench was studied numerically and the safety factors of the enclosure system met the specifications and the surrounding environment exceeded the control Indicators, the proposed soil reinforcement program to effectively control the construction of the substation due to the impact of the surrounding environment. In this complex environment, the feasibility of substation foundation pit project construction assessment and to optimize the design to ensure construction safety.
