摘　　要：谢赫哈利法特护医院项目整个通道均为地下建筑,全长180多m,设计为筏板基础,基础宽度达到7.7m,厚度为1m,板墙高度为2.5m,板墙厚度为30cm,顶板厚度为30cm。整个地下通道的施工流程按照基坑开挖,筏板施工,竖向施工,顶板施工,防水工程,基坑回填的工序进行,由于隧道较长,因此在整个施工过程中,对隧道进行分段分区施工,在保证工程质量的同时尽可能地缩短工期。主要介绍了整个通道施工的工艺流程及注意事项。The underground tunnel in Sheikh Khalifa Hospital is about 180 meters,which is designed as raft foundation with width of 7.7 meters and height of 1 meter.The wall and the roof of the tunnel is all 30cm height.The whole underpass is constructed by the process of foundation excavation,raft construction,vertical wall construction,roof construction,waterproofing construction and foundation backfill.Because it is longer,so the underpass is constructed by segments and zones which can shorten construction period on the premise of ensuring construction quality.This paper mainly introduces construction process and the attention items of the underpass.
