摘要
以捞刀河大桥8号墩深水浅覆盖层地质条件下的锁扣钢管桩围堰工程为背景,研究了其支护结构的优化设计与智慧监测应用。首先,通过有限元分析软件MIDAS GTS NX对围堰支护结构进行模拟分析,验证了原设计方案的合理性,并在此基础上提出了优化措施,包括调整钢管桩间距和利用现场废弃材料等。优化后的方案在满足设计规范要求的同时,显著提高了经济性和施工便利性。其次,结合智慧监测系统,构建了“设计-施工-监测-反馈”的闭环框架,实时监测围堰的应力、变形、水位和环境数据,验证优化设计的可行性,确保施工过程的安全性和可靠性。
Based on the lock⁃up steel pipe pile cofferdam project under the geological conditions of deep water and shallow overburden of No.8 pier of Laodaohe Bridge,the optimization design and intelligent monitoring application of its supporting structure are studied.Firstly,the finite element analysis software MIDAS GTS NX was used to simulate and analyze the cofferdam support structure,and the rationality of the original design scheme was verified.On this basis,the optimization measures were proposed,including adjusting the spacing of steel pipe piles and using waste materials on site,etc.The optimized scheme not only meets the requirements of design specifications but also significantly improves the economical efficiency and construction convenience.Secondly,combined with the intelligent monitoring system,a closed⁃loop framework of“design⁃construction⁃monitoring⁃feedback”has been constructed to monitor the stress,deformation,water level,and environmental data of the cofferdam in real time,verify the feasibility of the optimized design,and ensure the safety and reliability of the construction process.
