“…This may result in increasing pile deformations and altering the distribution of internal forces in piles, pile caps, and the supported superstructure [e.g. see [4][5][6][7][8][9][10]. Various empirical relationships between tunnelling induced ground movement and associated structure damage were introduced based on the analysis of previous case histories [11][12][13][14][15][16][17][18].…”

This paper investigates the interaction between tunnelling in soft soil and adjacent piled structure. Several three-dimensional finite element analyses are performed to study the deformation of pile caps and piles during the construction of a nearby tunnel. The comparison between free field analyses with those of coupled analyses is also presented. To simulate the tunnelling process and its effects on piled structures, one symmetric half of the soil medium, the tunnelling boring machine, face pressure, the final tunnel lining, the pile caps, and the piles are modelled in several construction phases. The paper is organized into three parts: the first part describes the adopted numerical model; the second part investigates the response of pile caps during tunnelling; and the last part is concerned with the deformation of piles in the presence of the superstructure.

“…The existing researches show that: the changing regularity of advanced displacement in front of working face during tunnel excavation, which is usually determined by 3-D numerical analysis and empirical equation with the specific description of advanced displacement curves, can be used to forecast the development trend of surrounding rock deformation with the propulsion of working face and calculate the total surrounding rock deformation (Schubert et al, 2002;Sun, 1996;Sulem et al, 1987;Schubert and Steindorfer, 1998;Carranza-Torres and Fairhurst, 2000;Yang et al, 2011). The changing conditions of radial displacement at certain point of tunnel surrounding rock The advanced displacement curves indicate the changing conditions of radial displacement at certain point of tunnel surrounding rock in front of working face showed in Fig.…”

Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-plastic numerical simulation relying on Liangshui tunnel of Lan-Yu railroad is conducted on mechanical behaviors and deformation steric effect of tunnel construction and the calculation results are compared with the modeling data. The research results show that: the steric effect of excavation face is the dominant factor in the incidence of working face and the stress of surrounding rocks gradually releases from excavation face; the range of 0.5~1 times the cave diameter around rock mass in front of working face is the disturbance range and the key area of stabilization and reinforcement for wake surrounding rock. According to the analysis and construction practice, the supporting structure of large-section tunnel with weak surrounding rock should be established as soon as possible to control the displacement change of surrounding rock in the range of load-bearing ring, reduce disturbance and improve the self-bearing capability of surrounding rock. Because of the distinct excavation steric effect of weak surrounding rock, the secondary lining structure must be established in time to bear the later pressure and restrict the large displacement of surrounding rock. The research results can provide reliable basis for engineering stability control of analogous tunnels.

A development of underground space is very useful solution to slove problem occurred from ground surface enlargement in urban areas due to the growth of population, tunnelling is the most popular way and widely used. Researches regarding tunneling-induced pile-soil interactive behaviour have been conducted by many researchers. A study on pile axial force distribution due to tunnelling through laboratory model test, however, is being rarely carried out. In this study, therefore, authors investigate ground behaviour due to tunnelling below grouped pile subjected vertical load as well as pile axial force distribution. A concept of volume loss is used to express tunnel excavation, which is normally applied to 1~2% for tunnelling in soft ground. In this study, however, 10% of that applied to investigate failure mechanism. As a result of laboratory model test, a decrease of pile axial force occurs at 1.5% of volume loss, settlement of grouped pile is 1.2~4.7 times greater than the adjacent ground surface one. Ground deformations at 1.5% of volume loss are measured using Close Range Photogrammetry and compared with results from numerical analysis.
