| 摘 要： | 以浦东机场进场路地道改建工程为例，重点对为满足地下道路不间断运营工况的地道结构进行受力分析及施工步序研究。解决了传统地下通道改扩建工程需要封闭地下道路交通的难题，即整个施工期间地下交通仍能不间断运营。方案在国内尚属首例，具有标志性意义。

| Abstract: | Taking an underpass reconstruction project of the access road in Pudong Airport as an example, the stress analysis and construction sequence research of the underpass structure are carried out in order to meet the uninterrupted operation of underpass. The problem that the traditional underpass reconstruction and expansion project is required to close the underground road traffic is solved, that is, the underground traffic can still operate continuously during the whole construction period, which has the symbolic significance. |

| Keywords: | underpass uninterrupted operation construction procedure reconstruction and expansion steel support conversion |
