摘要
桩基主动托换技术适用于对变形要求严格的工程。通过对超静定桥梁的施工影响分析,掌握其变形特点和施工控制要求,制订出行之有效的主动托换设计和施工方案。通过对施工全过程动态化监测,验证了设计方案的有效性,保证了桥梁的安全和工程的顺利实施。
Pile foundation underpinning technology is suitable for the strict requirements of the engineering deformation.Through the construction impact on statically indeterminate bridge analysis,in order to grasp the deformation characteristics and construction control requirements,the effective active underpinning design and construction scheme was formulated.Through dynamic monitoring of the whole construction process,this paper verified the validity of the design scheme,which ensured the smooth implementation of the safety of the bridge and engineering.
