超高层建筑深基坑开挖及结构回筑对近距离相邻地铁区间结构的影响分析

随着上海地下轨道交通事业的不断发展,越来越多的高层建筑紧邻地下轨道交通结构进行建设。为达到保护地下轨道交通结构的目的,需分析基坑开挖至结构回筑施工全过程对地下轨道交通结构的影响。应用三维有限元法,分析某超高层结构从基坑开挖至结构回筑全过程对紧邻地下轨道交通区间隧道的影响,并从中得到区间隧道的变形规律。

Influence Analysis of Deep Pit Excavation and Structure Construction of Super-high Rise Building on Interzone Structures Adjacent to Subway

With the continuous development of subway traffic undertaking in Shanghai,more and more high-rise buildings are constructed closely to the subway traffic structures.To achieve the goal of protecting the subway traffic structures,it is necessary to analyze the influence of the whole process from the pit excavation to structure construction on the subway traffic structures.The article analyzes the influence of the whole process from the deep pit excavation to the structure construction of a super-high-rise building on the interzone tunnels adjacent to subway traffic,and achieves the deformation rule of the interzone tunnels by using the 3D finite element method.
