In this paper, the way how to install the pipe-shed for whole length to the tunnel, how to link up all working procedures and how to form a loop to prevent the deformation of surrounding rock are introduced.

The longitudinal deformations of the pipe-roofs in the entrance of Tujiangchong tunnel are monitored by installation of a series of strain gauges to investigate the mechanical behaviors of the pipe-roofs during the tunnel excavation;and the working mechanism of pipe-roofs in shallow tunnels is discussed.

The article applied finite element method to analyze the stresses of box culvert structure advanced in pipe-roof under various operating modes,and the results show that the validity and rationality of our design.

The paper introduces the major technologic measures of the construction of the pipe-roofs and the ground settlement control methods,analyses the distortion mechanisms of the pipe-roofs and compares the mea.
