摘　　要：隧道的开挖卸荷会引起周围土体扰动变形,导致近接既有桩基础产生附加变形和内力,影响上部建(构)筑物的安全使用,研究盾构隧道对既有桩基的影响具有十分重要的意义。文中从隧道模型、桩基模型、试验土体材料、试验条件、研究内容等方面对现有的双线隧道模型试验研究成果进行归纳和总结。在此基础上提出进一步的研究思路和研究方向,为后续模型试验研究提供参考。The excavation and unloading of shield tunnel causes disturbance and deformation of surrounding soil, resulting in additional deformation and internal force of adjacent existing pile foundation, and affecting the safe use of upper buildings(structures).It is of great significance to study the impact of shield tunnel on existing pile foundation.We summarizes the existing research progress of side-by-side twin tunnel model test from the aspects of tunnel model, pile foundation model, test soil materials, test conditions, and research contents. Further research ideas and research directions are put forward, which may provide the reference for the following research.
