Studies on the Key Technologies for Underground Construction of High-Speed Ra…
Using the practice of Ningbo high-speed railway station transportation hub as an example, we studied and reported on the key technologies for the construction of an urban railway transportation hub that integrated the functionalities and structures of a railway, subway, city bus, and taxi stations for traffic and passenger transportation. Specifically, we first studied the impact of deep founda…
Shearing Behavior of Segmental Joints of Large-Diameter Shield Tunnel
Segments floating is often encountered during the large-diameter shield tunneling. Shearing resistance of circumferential joints is of great importance for resisting the tunnel floating. The shearing resistance in terms of circumferential joint dislocation is studied using 3D numerical simulation. The influences of bolt types, gaskets, transmission cushions, and longitude bolt pre-force on the …
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 …
Progress of Research Advance on the Model Tests on the Interaction Between Ne…
The model tests on the interaction between new constructions and adjacent existing buildings were summarized and analyzed from four aspects: the preparation methods of the model soil, the selection of pile model and tunnel model, the simulation methods of excavation process, and the loading methods of model tests. Several conclusions can be drawn as follows: (I) the influence of the superstruct…
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…
