以某高速公路特长隧道膏盐地质段施工为例，介绍在膏盐段施工过程中应采取的措施及必要的技术手段，确保隧道在开挖施工过程中结构安全，保证隧道建成后的运营安全及寿命，为以后类似地质段隧道施工提供借鉴。

Taking the construction of the gypsum section of a superlong highway tunnel as an example, the paper presents the technical measures taken during the construction of the gypsum section of the tunnel, so as to ensure the structural safety of the tunnel during excavation construction and to guarantee the operation safety and service life of the tunnel. The paper can provide reference for the construction of tunnels in similar geology in the future.
