摘　　要：地下变电站一般建于用地紧张、周边建筑密集的市区,埋深较深,防水要求高,外围护多采用地下连续墙与内衬墙相结合的叠合墙或复合墙。叠合墙技术虽然在已建地下变电站工程中广泛应用,但由于其本身局限,无法满足《建筑与市政工程防水通用规范》对一级防水的要求。本文结合上海110 kV甘肃地下变电站,对复合墙、叠合墙方案进行对比分析,对不同内衬墙、地下连续墙厚度组合进行受力分析与经济性分析,结果表明:采用复合墙方案时,内衬墙弯矩更小,从而可以获得更经济的配筋,在满足结构安全和裂缝控制要求下,具备更优的经济性。Underground substations are generally built in urban areas with tight land and dense surrounding buildings,with deep burial depth and high waterproof requirements,and the composite wall or laminated wall combined with diaphragm wall and interior wall are used for peripheral protection.The laminated wall technology is widely used in existing underground substation projects,but due to its own limitations,it cannot meet the requirements of General Code for Waterproofing of Building and Municipal Engineering for first level waterproofing.This article compares and analyzes the laminated wall and composite wall schemes in 110 kV Gansu underground substation in Shanghai,and conducts stress and economic analysis on different thickness combinations of interior walls and diaphragm wall.The results show that when the composite wall scheme is adopted,the bending moment of the interior wall is smaller,so that more economic reinforcement can be obtained,and the requirements of structural safety and crack control can be met with better economy.
