随着我国社会经济的高速发展,对资源的利用和需求与日俱增,近年来我国对西藏的资源开采力度加大。而西藏地处高原,生态环境极其脆弱,故在基础工程的建设中环境保护已成为重点,在矿山开采运输中为了不破坏环境,尽可能的考虑地下运输。故长隧道的建设已成为必不可少的建设项目,大长隧道的通风问题也就成为施工中的重中之重。现以西藏华泰龙甲玛工程项目的主平窿建设为例,对高原长隧道施工中的通风问题做一探讨。
With the rapid socio-economic development in our country, the utilization and demand of resources are increasing day by day. In recent years, our country has taken more efforts in exploiting resources in Tibet. However, Tibet is located in a plateau where the ecological environment is extremely fragile. Therefore, environmental protection has become a key issue in the construction of basic works. In order to avoid damaging the environment in mining and transportation, underground transport should be considered as much as possible. Therefore, the construction of a long tunnel has become an indispensable construction project. The ventilation problem of the Long Tunnel has also become the top priority in construction. Taking the construction of Huatai Longjiama Project in Tibet as an example, this paper discusses the ventilation problems in the construction of long tunnel in plateau.
