摘　　要：结合紧邻越江隧道的深基坑工程,对基坑支护形式进行了优化。施工过程中对越江隧道的变形控制采取了针对性的技术和施工保护措施,有效控制了基坑及越江隧道的变形,保障了对越江隧道的结构安全和正常运营,收到了良好的效果,相关措施可为今后类似工程的施工提供经验借鉴。Combined with the deep foundation pit project adjacent to a river crossing tunnel, the support form of the foundation pit is optimized. During the construction process, the targeted technical and construction protection measures are taken for the deformation control of the river crossing tunnel, which effectively control the deformation of the foundation pit and the river crossing tunnel, ensure the structural safety and normal operation of the river crossing tunnel, and receive good results. The relevant measures can provide experience for the construction of similar projects in the future.
