“…Analogous to the concept of the soil stress-strain hysteresis cycle under cyclic load, it is possible that the soil can adjust the dislocation between particles during multiple cycles. The energy consumed by the sliding shear and friction gradually decreased, and the viscous damping of sand particles also decreased [20,37]. Load-displacement curve in the initial cycle is not closed as the soil is in the initial dense state exhibiting strong particle interlock.…”

“…When the ground suffered from continuous disturbances induced by alternant downward and upward movement, the initial stress state of the adjacent soil will be affected as the redistribution of stress related to ground deformation occurred. The relative density of soil will change after the previous disturbance, which significantly affects the strength-deformation properties and the degree of particle interlocking [20,37]. Load evolution and load transfer mechanisms are thus affected [2,56].…”

In the classical conception of the arching mechanism, the well-known trapdoor problem assumes distinctive modes (e.g., either active or passive mode) in the original geostatic overburden pressure. However, in various geotechnical applications, underground inclusions or structures may experience alternant upward and downward movements induced by construction activities or environmental changes, leading the ground to be initial loss or compaction state. If the initial disturbed state occurs, the estimation of vertical load on structures is improper based on classical trapdoor mechanism. In this study, a new conception, alternant active and passive trapdoor problem was introduced. Using a comprehensive measured system, such as particle image velocity technique and various sensors, alternant active and passive trapdoor tests were conducted to explore the mechanical behavior and kinematic mechanism of the backfill subjected to continuous loading and unloading. The development of arching with trapdoor displacement was visualized and quantified in different modes and states. Then, this problem was treated in a statical analysis based upon the visualized kinematic mechanisms. Solutions for the trapdoor load in the typical development states of arching were calculated by limit equilibrium method. Finally, two simplified ground reaction curves representing the progressive development of arching were proposed to facilitate in engineering applications. The simplified method was verified by the trapdoor test results.

“…In recent years, advancements in technology have influenced how designs are conceptualized, considering sustainability aspects [1][2][3][4], challenges faced in laboratory soil tests [5,6], soil-structure simulations [7,8], and inferior in situ geomaterial conditions requiring biological [9][10][11][12][13][14] or chemical stabilization [15][16][17]. For instance, the study of the effects of the interface on soil-structure interactions have benefitted from this technological advancement to include the design of deep foundations [18][19][20][21][22][23], pavement-subgrade behavior [24,25], tunneling [26][27][28][29][30][31][32][33], mechanically stabilized geogrid retaining walls, and ground improvement in soft soils [34][35][36]. For example, in the design of deep foundations, static and dynamic pile load tests provide the necessary evidence-based field observational results to verify the accuracy and reliability of the initially adopted pile design parameters.…”

The study of soil–structure interface behavior contributes to the fundamental understanding of engineering performance and foundation design optimization. Previous research studies the effect of soil characteristics and surface roughness property on the soil–material interface mechanism via interface shear test. The reviews utilizing past established laboratory studies and more recent tests based on state-of-the-art technologies reveal that surface roughness significantly affects interface shear performances in the studies of soil–structure interactions, especially in peak shear strength development. A preliminary but original investigative study by the authors was also carried out using a sophisticated portable surface roughness gauge to define the material surface roughness properties in order to study the interface behavior parametrically. Additionally, using the authors’ own original research findings as a proof-of-concept innovation, particle image velocimetry (PIV) technology is applied using a digital single-lens reflex (DSLR) camera to capture sequential images of particle interactions in a custom-built transparent shear box, which validate the well-established four-stage soil shearing model. The authors also envisaged that machine learning, e.g., artificial neural network (ANN) and Bayesian inference method, amongst others, as well as numerical modeling, e.g., discrete element method (DEM), have the potential to also promote research advances on interface shear mechanisms, which will assist in developing a greater understanding in the complex study of soil–structure interactions.

“…Taking into account the uncertainty of the geological lithology and the complexity of the construction environment, more consideration should be given to the soil-structure interaction during tunnel construction, and efforts should be made to reduce the adverse impacts of tunnel construction [1][2][3]. In particular, in urban areas, because of the interaction between the soil and the structure, the disturbance caused by shielding construction may reduce the safety of roads and pipelines [4,5]. When a tunnel crosses pipelines at close range, it can easily cause ground settlement and deformation or even the destruction of the pipelines [6,7], which will seriously affect the production and life of the surrounding residents and result in negative economic and social impacts.…”

Shielding tunnel construction always has negative impacts on the surrounding buildings. Because of repeated disturbances caused by the construction, more attention should be paid to the impacts of the nonsynchronous construction of a twin-tunnel. In this research, a three-dimensional model was established to simulate the construction process of a twin-tunnel in a section of the Hefei No. 4 metro line, and the calculation results were validated with the measured settlement data. Based on the model, the ground settlement and the existing pipeline responses were studied in detail. The results showed that, after the first tunnel (FT) construction, the settlement curves conformed to a Gaussian distribution. Additionally, after the second tunnel (ST) construction, the final settlement curves were no longer completely symmetrical. The influences of the twin-tunnel space and the pipeline-soil relative stiffness on the settlements were further studied. The results showed that the final settlement curves of the ground surface and the pipeline were mainly W-shaped, U-shaped, and V-shaped. As the twin-tunnel space increased and the pipeline-soil relative stiffness decreased, the settlement curve gradually changed from V-shaped to W-shaped. C was defined as the ratio of two maximum settlements in the W-shaped settlement curve. As the space increased, C started to decrease from 1 and then increased to 1.
