In China, there are 15,181 highway tunnels with a total length of 14,039.7 km have been put into service by 2016. Tunnel lining cracks is the most critical risk, therefore, how to control the structural safety of highway tunnels has become one of the prominent issues. In this paper, effects of length, width, depth and position of highway tunnel lining cracks on the safety of lining structure ha…
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…
The filter cake on the tunnel face has a significant influence on project of the slurry-driven shield. During the excavation, only permeable filter cake is allowed to form because the rotating speed of cutter wheel is fast. Through the filter cake, the water of slurry will infiltrate into the soil. The water enhances the hydraulic head and the risk the failure of tunnel face. In order to determ…
This paper presents an investigation on the behavior of a cofferdam structure constructed by double sheet pile walls above the muck, which is used to construct the inner foundation for an immersed tube tunnel project in GuangZhou China. A detailed three-dimensional FEM model is formulated to simulate the whole prosesse, including the construction of the cofferdam and the excavaction of the inne…
Synchronous grouting is one key procedure to backfill the construction gap and control the ground subsidence. The grouting prsessure and grout properties are key construction factors that dominate the consequence of synhronous grouting. To investigate the effect of these factors, a novel framwork to simulate the process of synchronous grouting is proposed in this paper. LOKASI: Ruang Koleksi…
