明洞

而采用明洞方案可以最大限度地隔离大风环境与列车运营环境，防风效果好，但存在工程费用高、运营环境较差、施工不便及维修养护工作量大等问题。

The scheme of open cut tunnel can maximize the isolation of wind environment from the train operating environment . The windproof effect is good , but there are problems of high costs , poor operating environment , inconvenient construction work and large amount of repair and maintenance work .
