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…
Analytical Solution of Underneath Tunnelling-Induced Deformation of Existing …
Tunnelling underneath the existing tunnels are very common these days. It is obvious that the under-crossing tunnelling will affect and even damage the existing tunnels. An analytical method is proposed in this paper to better understand the effects of the under-crossing tunnelling on the existing tunnel. The existing tunnel is modeled as a Timoshenko beam lying on a Kerr foundation. The validi…
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…

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…
A Prototype Load Test on Fracture and Damage Properties of Cracked Shield Tun…
In this paper, a prototype load test on cracked shield tunnel lining segment was conducted to study fracture properties of the segment with initial crack. Principle and process of the test were introduced, and test phenomena were detailedly depicted. Experimental results reveal that lining segment with initial crack finally shows the I-type fracture property, and the failure mode is dominated b…
