摘要
针对地铁下穿对机场高速公路路基的安全影响展开分析,首先综合各类规范及现有工程经验,确定安全影响评判标准;其次采用三维有限元模拟地铁盾构下穿施工过程,分析下穿施工对之上高速公路路基的影响;最后利用分析结果及评判标准,评价地铁施工时公路路基的安全状况。
The paper analyzed safety impact on the roadbed when subway crossing the airport highway. First according to various specifications and engineering experience,determined the impact safety standards. Second,used the finite element simulation the construction to analyze the impact. Finally,had the evaluation of safety status of roadbed during the crossing construction.
