| Abstract: | Combining the construction of Yunling Tunnel of Shiman Expressway, the form and developing process of floor heave in tunnel are described. Several factors affecting floor heave are studied. By analyzing the stability of the invert of tunnel, a formula for calculating floor heave is obtained; and then verified by the data of spot monitoring. By analyzing the mechanism of floor heave of tunnel, the deformation damage mechanism of rock mass is understood correctly and the disposal measures of floor heave are prescribed. The research not only can provide basis to optimize the supporting system of tunnel, but also to guide construction process and insure constructive safety. |
