Abstract:
Comparison and contrast is made among different tunnel portal construction technologies in terms of economical efficiency and practicability, so as to select proper construction technologies for the bambootruncated portals of Lafashan tunnel. In the end, technologies, including preparing formworks for the extended section of the tunnel portal, settingout of the formworks, fabrication of the formworks and installation of the formworks, are adopted for the tunnel. In this way, integral portal is cast rapidly by means of the existing formwork jumbo.
Key words: Lafashan tunnel, bamboo truncated portal, formwork jumbo
