“…The simulation of tunneling using EPB techniques was conducted in this study, involving the modeling of shield tunnel advancement according to a step-by-step approach with a step of 1.2 m, corresponding to the tunnel lining width. The TBM construction process, summarized by Lueprasert et al [13], commenced with the assignment of initial field stress based on the soil stratigraphy and water level to achieve geostatic equilibrium. The initial stress was determined by adjusting the lateral earth pressure at rest and soil unit weight corresponding to the soil type.…”

“…Figure 5 illustrates the validation of the simulated results using the measured field settlement presented by Suwansawat [14]. Referring to the detailed information on TBM mentioned in the previous section, a uniform contraction ratio of 1.3% was applied to achieve the corresponding outcome, which corresponds to the value adopted in previous studies [11,12,13].…”

In dense urban areas, tunneling can potentially lead to structural damage or compromise the integrity of nearby buildings, thus necessitating a thorough evaluation of its impact during the design phase. Various engineering methods exist to estimate building responses to adjacent tunneling, each varying in complexity. These methods yield different outcomes, such as settlement magnitude and behavior. This study examines pile settlements, differential pile settlement, and angular distortion of a building through three distinct analysis methods. These involve two-step methods of soil-structure interaction of a building and tunneling from (1) the corresponding greenfield ground, (2) piles embedded in the ground, and (3) piles under loading. The results were then compared and discussed. Based on the obtained results, the method for considering piles under loading can be regarded an effective method for providing a conservative evaluation.

“…It had been suggested that a certain technique for tunnel deformation be used. In addition, the shape of the deformation of the tunnel is a rotating ellipse or kidney shape in the case of the pile tip below or above the tunnel lining, as clearly explained by Lueprasert et al (2023) [22]. Zheng et al (2017) [23] used the finite element method to determine the tunnel deformation characteristics brought on by excavations.…”

Deep foundations are frequently built close to existing tunnels in the urban environment. Tunnels can only withstand very small movements. The construction of bored piles and/or the subsequent loading of the piles may result in unbearable movements or stresses that could result in cracking of the tunnel linings, which worries obstacles to the tunnel structure. This research presents an understanding of the interaction issue and investigates and evaluates various geometric factors that determine the effect of the construction of the pile on the existing tunnel. However, numerical modeling was established utilizing a modified Mohr-Coulomb constitutive model for the soil strata. Numerous factors have been examined, including different locations of the pile tip to the tunnel centerline as well as variable pile diameters and lengths. The numerical analysis results revealed that the bending moment decreases as the distance from the tunnel increases from 8 to 12 m and then remains constant, while the shear stress is not affected considerably. In addition, the shear stress and bending moment increase with pile diameter and length due to the increased confinement caused by the pile. The spacing has a considerable effect on the horizontal displacement with very little effect on the vertical displacement. Moreover, there is an increase in the shear force developed in the tunnel lining with pile diameter for different spacings between the tunnel and pile. This increase becomes smaller as the pile length increases. At small spacing between the pile and tunnel (8.3 m and 12.5 m), the bending moment in the tunnel lining decreases as the pile length increases. Doi: 10.28991/CEJ-SP2023-09-016 Full Text: PDF
