“…However, a common limitation in most of these analytical studies is the assumption of a rigid (nonyielding) retaining wall, harmonic motion, or linear amplification of backfill acceleration. In reality, retaining walls undergo deformation, seismic motion is nonharmonic, and amplification is nonlinear [27]. Over time, efforts have been made to address these limitations, with some analytical studies featuring the nonlinear amplification of backfill acceleration under horizontal harmonic motions [28][29][30].…”

Given the abundance and importance of earth retention structures, the problem of seismic earth pressure has attracted not only the research community but also industry and government establishments. The dynamic response, even in the case of the simplest retaining wall, presents a complex problem of soil–structure interaction, encompassing a multitude of competing and complementary factors. This article presents a thorough and critical evaluation of notable analytical and field studies related to the dynamic earth pressures acting on retaining walls. Despite numerous studies spanning nearly a century regarding seismically induced lateral earth pressures, there remains a noticeable disparity between theoretical understanding and the actual field performance of retaining structures during seismic events. This review underscores the necessity for a more meticulous examination of dynamic analysis techniques and the existing design methodologies for retaining structures.

“…Wang et al [4,5] took the inverted siphon of Nansha river as the research object and analyzed the dynamic response of the inverted siphon under different working conditions; however, they did not consider the interaction between pipes and soil; Xu et al [6] carried out the dynamic response analysis of Xiaqin River inverted siphon under the excitation of bidirectional seismic waves, but they did not consider the influence of water in the pipe; Ai and Li [7], taking into account the joint action of soil and groundwater around the pipeline, adopted the nonlinear material constitutive model and analyzed the dynamic response of the underground pipeline through the effective stress method; Fu and Gu [8] used two-dimensional uniform equivalent viscoelastic artificial boundary conditions to summarize the response law of highway mountain tunnel under earthquake action; Han et al [9] analyzed the seismic response of the subway station under the action of near-and far-site seismic waves based on ABAQUS and gave the location of subway station vulnerable to damage under the action of earthquake. Qu et al [10,11] developed an analytical model in modeling the dynamic responses of the pile, anchor cable, and soil slope system based on Winkler elastic foundation beam theory. Although the research objects of literature [7][8][9][10][11] are pipeline structure, tunnel structure, subway, and pile wall structure, they provide ideas for the author's research.…”

Large-scale inverted siphon is a key hydraulic structure for building a national water network and realizing the spatial balance of water resources, and its safety under the action of earthquakes has become the focus of trans-basin water transfer projects. In this paper, Xiazhuang inverted siphon of water diversion in Central Yunnan is taken as the research object. Viscoelastic artificial boundary was used to simulate seismic waves spread in the soil, which include the natural site seismic waves and the waves fitted manually according to the site conditions. A three-dimensional finite element model of soil-structure-fluid interaction was established by software of ABAQUS, in which the fluid-structure interaction was simulated by user-defined element (UEL) built on additional Mass Method. Seismic response and damage analysis of large inverted siphon structure are carried out by the model. The results show that the dynamic displacement of the inverted siphon pipe is mainly horizontal sloshing, and the dynamic response of the pipe increases due to the water in the pipe; even the dynamic stress value in some areas is close to the design value of the concrete tensile strength. The damage analysis of inverted siphon pipe shows that the plastic deformation and the damage area develop rapidly with the increase of the peak ground acceleration (PGA), and the tensile damage area is generally larger than the compression damage area. The damage factor of the pipe under the working condition of the water is obviously larger relative to the working condition of no water. Therefore, it is suggested that the damage effect of earthquake should be considered in the design of large inverted siphon in high-intensity area.
