摘要
以某浅埋隧道为例,比较明挖法、回填贫混凝土反压法、套拱法三种方案施工的优缺点,选定套拱法对露顶段进行施工,并探讨应采取的施工安全措施。
Taking one shallow tunnel as the exsample,it compares the advantages and disadvantages of three consruction methods which are open surface method,backfilling lean concrete back pressure method and arch setting method,and chooses arch setting method to construct exposed top section.Finally,it explores the safety countermeasures for construction.
