Numerical Analysis of Ground Displacement and Pile Response Due to Tunneling …
The additional pile response due to the creep behavior of the soil is disadvantageous to the safety of pile. However, in the current studies for considering the creep behavior of the soft soil, the pile response induced by the long-term settlement of soil is seldom investigated. This paper mainly discusses the pile response during the excavation and operation periods considering the creep behav…
A Coupled Hydro-Mechanical Modeling of Tunnel Leakagein Sand Layer
The tunnel leakage in sand layer plays an important role in the evolution of the lining stresses and the ground movement. The phenomenon of internal erosion occurs when underground water leaks into the tunnel from the damaged joints or the cracks of the linings. Fines in sand are pulled off by seepage forces and transported throughout the soil matrix into the tunnel. The loss of fines due to se…
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 …
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…
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…

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…
