摘要
为减少基坑的变形,确保基坑的安全性与稳定性,探讨和研究了基坑内支撑体系中换撑技术。在确保围护结构安全与稳定的前提下,对车站基坑内支撑体系进行了优化创新。通过对附加水平钢管的设置优化,按照750mm的水平和竖向间距进行布置,水平钢管的内力和架体的变形均能满足要求,确保了天津地铁6号线洞庭路站保质保量完成。
In order to reduce the deformation of the foundation pit and ensure the safety and stability of the foundation pit,technology of bracing in the support system of foundation pit is introduced.On the premise of ensuring the safety and stability of the retaining structure,the optimization of the support system of the pit foundation is carried out.By optimizing the setting of additional horizontal pipe,arranged according to the horizontal and vertical spacing of 750 mm,the level of steel frame internal force and deformation can meet the requirements to ensure the completion of the Tianjin Metro Line 6 Dongting Road Station quality.
