The deformation characteristics of a weak foundation with high back siltation in an immersed tunnel lack empirical data; however, the calculation method and control of foundation settlements are highly important to tunnel design and construction. This paper takes a cross section of the natural foundation of an immersed tunnel in the Hong Kong-Zhuhai-Macao Bridge (HZMB) as the research object and conducts a centrifuge model test. The soil layer is divided, and the soil parameters are determined by the CPTU and the indoor dynamic three triaxial test. In consideration of the actual engineering scale and the ability of the centrifuge model test system, the similarity ratio of the model to the prototype is studied and determined. As for the immersed tube structure, the deformation characteristics are mainly studied. Therefore, the organic glass is selected as the model material by the similarity of the elastic modulus and the density. The characteristics of the resilience and recompression of the natural foundation of the immersed tunnel and the strain characteristics of the immersed tube structure are obtained by the analysis of the multiworking condition test data. Moreover, based on the actual engineering geological conditions of the subsea tunnel, a numerical calculation method is carried out to check the reliability of the centrifuge model test results. The results of the numerical calculation are consistent with the model test results.

“…According to equation (16), adopting steel fiber concrete can improve the bond characteristic of the interface (σ 24hb ) and thus increases the safety distance of shotcrete. (2) Operation sequences in tunnel excavation can be ordered to reduce blast charge and therefore significantly controls blast vibration [21,44]. A certain distance should be kept between upper and lower benches to keep the shotcrete from being repeatedly disturbed by blasting in a short time.…”

e drill and blast method is widely used in constructing tunnels in rock. Unfortunately, blasting vibration can damage newly performed shotcrete layers which are major support structures to stabilize surrounding structures. erefore, investigation of the influence of blasting on shotcrete and determining reasonable distance between blasting work face and shotcrete position is of great importance. In this paper, a large-span tunnel excavated by drill and blast method acting as a high-speed railway station has been investigated. Blast vibration in the tunnel was recorded using microseismic monitoring technique. Empirical prediction equations for peak particle velocity (PPV) were obtained through regression analysis based on the obtained monitoring data. e attenuation law of tensile stress imposed on shotcrete layer due to blasting and bond strength of shotcrete-rock interface was also investigated. Minimum safety distance between shotcrete and blasting positions was calculated based on bond failure criterion. Evolution law considering different factors including blasting charge, rock mass class, and setting time of shotcrete was also obtained, which could be applied to determine blast charge shotcrete arrangements for tunnel constructions in future. e obtained results showed that the safety of shotcrete could be ensured and shotcrete falling off the rock could be prevented under current blast constructions.

“…The simulation value has the same trend as the field monitoring value, as shown in Figure 13. At the beginning (stage [13][14][15][16][17][18][19][20][21][22][23][24], with the excavation at point A (stage 13), the settlement of the arch at point A in Z direction changes more rapidly, which is caused by the disturbance of lining structures when excavation. Then, with the continuous excavation (25-36 stages), the disturbance of point A in the subsequent excavation process decreases gradually, and the settlement of point A in Z direction tends to be stable.…”

“…However, with the development of BIM technology, its modeling method has not been improved greatly. As an underground project, tunnels have higher complexity than above-ground buildings, and the traditional modeling method for buildings is not suitable to the tunnel BIM [20]. Thus, it is necessary to study the modeling methods applicable to tunnel BIM [21][22][23].…”

Referring to CATIA's 'assemblies + parts' modeling method, CATIA-based BIM (Building Information Modeling) technology has been proposed for highway tunnel design in this paper. A tunnel BIM is created by CATIA, which is based on a real case in China, focusing on the following 3 aspects: (1) Creating tunnel bolts by UDF + Loop cyclic arrangement method; (2) Using Sketch Tracer module to create tunnel portal; (3) Parameter is used to create and call the Catalog database. Then, bolt collision inspection and U-shaped groove concrete statistics are conducted with the help of the tunnel BIM created. Finally, the finite element analysis of tunnel construction process is carried out through the CATIA-Midas interface. The results demonstrate that the CATIAbased BIM technology can well adapt to the characteristics of tunnel and have well potential applications in tunnel design.
