摘要

通过离心模型试验和数值分析，研究干砂地层开挖对相邻隧道的影响及隔墙的防护作用。创新性地将DIC位移测量技术引入离心机模型试验中，测量土体位移，确定开挖过程中隔墙桩影响范围内土体的牵引区和阻塞区近似范围。提出了隔墙桩对隧道位移控制效率的经验公式。试验结果表明：隔墙桩对浅土层起屏障作用，对深土层起牵引力作用。数值计算结果表明，桩长和桩顶埋深的增加先提高后降低隧道水平位移的控制效率。

Control effect of partition piles on tunnel horizontal displacement during excavation based on DIC displacement measurement technology

Centrifuge model tests and numerical analysis were conducted to study the impact of excavation in dry sand strata on adjacent tunnels and the protective effect of partition walls. The DIC displacement measurement technology was innovatively introduced into the centrifuge model tests to measure soil displacement, determining the approximate range of the traction and blocking zones of the soil within the influence range of the partition piles during excavation. An empirical formula for the control efficiency of partition piles on tunnel displacement was proposed. The experimental results indicate that the partition piles act as barriers for shallow soil and as traction forces for deeper soil. The numerical results show that both the increase in pile length and pile top embedment depth first enhance and then reduce the efficiency of controlling the horizontal displacement of tunnels.
