摘要
文章基于南京某新城综合管廊工程,介绍了平行顶管法施工管廊设计要点,采用有限元数值模拟方法分析平行顶管法施工对周边环境的影响.结果表明,不同顶管顺序会影响土层变形量,应合理选择多线顶管的顶进顺序,并结合分析结果提出平行顶管施工全过程的控制措施,以达到因地制宜、降低对构筑物及周边环境影响的目的,可为类似工程提供参考.
Abstract
Based on a new urban comprehensive pipe gallery project in Nanjing,this paper introduces the design points of pipe gallery constructed by parallel pipe jacking method,and analyzes the influence of parallel pipe jacking method on the surrounding environment by finite element numerical simulation method.The results show that different pipe jacking sequences will affect the deformation degree of soil layer.Therefore,a reasonable selection of the jacking sequence for multi-line pipe jacking should be made,and control measures for the entire process of parallel pipe jacking construction should be proposed based on the analysis results,in order to achieve the purpose of adapting to local conditions and reducing the impact on structures and surrounding environment,which can provide reference for similar projects.
