Bilateral deep foundation pit excavation would cause the stress redistribution and large deformation of the adjacent tunnel, and even induce the lining structure cracking. This paper aims to investigate the deformation and stress response of tunnel to bilateral foundation pit construction. The Zhengzhou East High-speed Railway Station (Zhengzhou East HRS) was taken as an example to conduct the analysis. First, the numerical calculation software Midas GTS/NX was used to simulate the foundation pit construction progress, the deformation and stress of tunnel structure were discussed. Then, some field work about tunnel deformation was conducted and the deformation characteristics was studied. The results show that under the repeated disturbance of the bilateral foundation pit construction, the tunnel deformation increased fluctuatingly, with the cumulative uplift and convergent deformation of about 26 mm and 16 mm, respectively. In addition, the cumulative change of the lining stress at DM16 section inside the foundation pit was 6.02% greater than that at DM30 section outside of the foundation pit, indicating the effectiveness of the reinforcement measures.

双侧深基坑开挖会引起相邻隧道的应力重新分布和大变形，甚至引起衬砌结构开裂。本文旨在研究隧道对双边基坑施工的变形和应力响应。以郑州东高铁站（郑州东站）为例进行分析。首先，利用数值计算软件Midas GTS/NX对基坑施工过程进行模拟，讨论隧道结构的变形和应力。然后，对隧道变形进行了实地考察，研究了隧道变形特性。结果表明，在双边基坑施工的反复扰动下，隧道变形呈波动增大，累积隆起和收敛变形分别约为 26 毫米和 16 毫米。此外，基坑内DM16段衬砌应力累积变化比基坑外DM30段衬砌应力累积变化大6.02%，表明加固措施的有效性。
