As an important part of critical infrastructure, shield tunnel is widely used in urban area of China recent years. The safety of shield tunnel during construction and operation has drawn more and more attention. In the operational period, real time deformation monitoring is an effective way to help us to reveal the long-term deformation mechanism and control the lifetime safety of shield tunn…

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 …
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…

Compaction is one of the most important factors affecting the future performance of asphalt pavement. Hot mixture asphalt materials exhibit significant time-dependent response under mechanical and thermal loadings, which can involve elastic, creep and plastic permanent deformation. The irreversible permanent deformation part will generate compaction. Foam-type model has been considered an effic…
