Simplified Method for Calculating the Settlement of Exsisting Tunnel Induced …
Settlement induced by new tunneling is important in assessing the safety of existing tunnel. A Simplified setlement method for the existing tunnel was obtained based on the two-step method. Firstly, ground setlement induced by tunneling was calculated using experimental method and elastic method. Then the entire tunnel deformation can be calculated using elastic-foundation-beam model and the gr…
A New Form of Longitudinal Joint of Large Cross-section Segmental Tunnel Linings
The resistance of longitudinal joint is a crucial design parameter on the mechanical properties and structural behavior of precast tunnel segmental linings constructed by the Tunnel Boring Machine (TBM). Recently, with the increased dimensions and functions of the shield tunnel, the traditional bolted connection forms (e.g., straight bolts, inclined bolts, curved bolts) for segmental joints m…
In-Situ Experimental Analysis of Acceleration Response of Mountain Tunnel Lin…
Resonant rubblization technology is often utilized to rehabilitate deteriorated condrete pavements. Vibrations induced by a resonant breaker would produce detrimental effects on lining structures in tunnel during rubblization construction. The in-situ experiments were carried out in Yangjiao Mountain Tunnel in Zheijiang Province, China. First, the characteristics of rubblization-induced vibrati…
An Analytical Solution for the Failure Process of a Shiled Tunnel Segmental J…
The structure of a segmental joint with a load-transferring gasket is complicated and exhibits piecewise and nonlinear deformation characteristics under loads. Joint stiffness largely depends on the properties of the concrete and load-transferring gasket, which are the main components of the joint. A reasonable consideration of their influence is one way to predict the failure process of the …
Cutter Ring Breakage Induced by Unbalanced Side Force in Circular Cutting Pro…
The cutter ring breakage as a cutter failure mode in shield tunnel construction is more likely to occur in the centre zone of cutterhead. Given the inconsistence of this phenomenon with the linear cutting theory, the present paper suggests the use of the circular cutting theory to explain the cutter ring breakage and find the correlation between the unbalanced side force and cutter ring breakag…
