The invention discloses an implementation method of a tunnel monitoring multi-webpage interface on the basis of a multi-screen workstation. The implementation method comprises the following steps of providing a plurality of display screens, wherein any one display screen corresponds to one application window, and a plurality of application windows contain one main window and at least one extension window; carrying out user login on the main window, and storing user login information in a server; reading the user login information stored in the server to cause the expansion window to obtain a login permission so as to finish uniform authorization with the main window; displaying a corresponding information page in the main window and the expansion window. According to the implementation method, a plurality of pages in the same B/S framework-based tunnel monitoring system is called on each display screen simultaneously by the same user identity on each display screen on a one-machine multi-screen workstation, and information interaction and mutual calling between different pages can be realized. A user only needs to log in on the main window for one time to share the login identity and permission, and the tunnel monitoring system is accessed through the page on each application window.
