摘要

据相似材料大比尺三维概念物理模型理论，高仿真度制作了成型盾构隧道地铁站厅隧道开挖试验物理模型。模拟了双盾构隧道之间开挖站厅隧道的全过程，研究了站厅隧道、横通道开挖过程中模型地表沉降，土体的变形，盾构隧道及站厅隧道洞周特征点的位移。模拟并研究了混凝土加固桩对土体位移的影响，总结出土体的动态力学特征和变形规律，得出一些有益的认识和结论。对指导地铁施工、研究在已建成双隧道间拓展开挖站厅空间具有十分重要的意义。

Abstract

Based on the large scale conceptual model theory of similar material

a physical model of metro station tunnel excavation was simulated. The excavation process of metro station tunnel between existing double tubes also was simulated. Ground settling

soil deformation and displacement of specific points around tunnels were studied. The influence of a castinplace pile on reducing soil displacement was simulated. The dynamic mechanical behavior and deformation laws of the soil were obtained along with some useful conclusions. The conclusions are beneficial for guiding the construction and expanded excavation of metro station spaces between existing double tubes.
