Dynamic Response of Tunnel Lining to Resonance Rubblization Induced Vibration…
The resonance rubblization technology can be adopted to reconstruct old concrete pavement and eradicate reflection cracking. This method fractures pavement into fragments quickly and directly casts asphalt on fractures, shortening time cost of reconstruction. Previous studies about this technology mainly concentrated on asphalt-casting methods, and the quality, stiffness, and flatness of reco…

Research on Strength Charcteristic Parameter of Sandy Pebble Soil Based on Di…
Sandy pebble soil is widely distributed in our country. Lots of studies show that sandy pebble soil makes dynamic behavior not clear due to typical discreteness of gravels and random geometrical distribution. This paper quantitatively analyzes the law of the strength characteristics of sandy pebble tunnel surrounding rock under different density and moisture content conditions through large-s…
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…

Ground Penetrating Radar Inspection Experiment on a shield Tunnel Segment and…
With the purpose of testing the effectiveness and feasibility of Ground Penetrating Radar ( GPR) in settling a common construction quality problem which is the thickness estimation of backfill grouting, we conduct a field experiment in Shanghai. A shield tunnel segment, with half of its outer surface covered by a wooden box, is put vertically on the ground. We inject the concrete grout into the…
Mechanical Analysis of a Super-Large-Diameter Shield Tailskin Under Deep Grou…
The deformation and stress of a super-large-diameter shield tailskin are analyzed in this paper. Four kinds of structure analysis models, i.e. the perfect solid shell model, the defected solid shell model, the perfect hollow-layered shell model, and the defected hollow-layered shell model are formed to study the effects of initial geometrical defects and the hollow-layered shell formation on th…
Discrete Element Analysis of the Excavation Disturbance of Cross-River Twin-T…
The increasing number of twin-tunnels constructed in river-crossing subway traffic compels the designers to explore its dynamics performance in the excavation progress. The characteristics of particle accelerations of the granular medium in the surroundings are the important factors to reflect the excavation disturbance. In the construction process of the twin-tunnels, the excavation of the sec…
