“…Similar damping materials were used by numerous researchers. 35,[40][41][42]44,46,54 In present study, six reduced-scale 1-g shaking table tests were carried out to investigate the effect of the inclination angle of backfill material (𝛼 = 0 • , 5 • , 10 • ) and back of the gravity retaining wall (𝛽 = 0 • , 10 • ) and, input peak ground acceleration (𝑃𝐺𝐴) values on the seismic behavior of the gravity retaining wall. The test program followed in this study is summarized in Table 3.…”

In the present study, the seismic performances of gravity retaining walls having both inclined back side and inclined backfill were investigated under sinusoidal acceleration excitations using series of shaking table tests on 750 mm height physical model. The effects of input peak ground acceleration (𝑃𝐺𝐴), inclination angle of backfill material (𝛼) and inclination angle of back of the gravity retaining wall (𝛽) on acceleration amplification factor (𝑅𝑀𝑆𝐴), maximum peak lateral relative (𝑆 maxpeak(𝑟𝑒𝑙) ) and maximum residual lateral displacement (𝑆 max(𝑟𝑒𝑠) ) of the wall, surface settlement (𝑆 𝑠𝑒𝑡 ) of the backfill material, inertial force (𝑃 𝐼 ) and horizontal dynamic active force (𝑃 𝑑𝑦𝑛ℎ ) were assessed. It was observed that higher values of the 𝑅𝑀𝑆𝐴 were obtained from the experimental results as compared the ones from current seismic design codes. Moreover, the six results of shaking table tests revealed that the phase difference was appeared between the inertial force and dynamic earth pressures. Pseudo-static limit equilibrium methods resulted in over conservative 𝑃 𝑑𝑦𝑛ℎ results and could not truly reflect the seismic behavior of gravity wall due to the inertial forces and phase difference not taken into consideration.

“…Limited by its height, the T-shaped cantilever retaining wall could not contribute to the protection of the high-steep slopes. By conducting a scale model test, Zhu et al [6] studied the factors influencing the deformation mode of a gravity retaining wall and the failure mode of footings made of different materials. Liu et al [7] employed the pseudostatic method and limit equilibrium method to study the effect of embedded depth on the critical acceleration of a soil-wall system and quantified the seismic rotational stability of a gravity retaining wall.…”

“…In the Rankine Earth pressure theory, the positive active Earth pressure of the cohesive soil is due to the dead and external loads, and the negative active Earth pressure is due to the cohesive force. According to equation (6), the net force of the active Earth pressure acts (H(H + 3h)/3(H + 2h)) away from the wall toe. e horizontal component of the displacement vector of the retaining wall, described in Figure 9(b), can intuitively reflect the effect of the net force, consistent with Rankine Earth pressure theory.…”

Research on the retaining structures for high-steep slopes is extremely significant because of its real-world applications and far-reaching implications. A flexible geocell-reinforced ecological retaining wall as a high-steep slope protection scheme was developed and applied to the slope protection project of the Ji-Lai Expressway by analyzing the reinforcement mechanism of the geocell used. The lateral displacement and Earth pressure distribution on the flexible ecological retaining wall applied to the high-steep slope were studied using finite element numerical simulations and verified using field experiments. Results reveal that the wall maximum horizontal displacement is 2/3 H away from the wall toe because of the replacement of the upper part of soil. There is an obvious bucking effect on the active Earth pressure around the stiffened site, and the flexible deformation of the retaining wall helped effectively release some of the Earth pressure. Consequently, the measured value is lower than the theoretical value. Through this case study, it is demonstrated that the flexible ecological retaining wall as a slope protection technology can be successfully applied to steep slopes with a height of more than 15 m. Moreover, it brings significant advantages for protecting the ecological environment and improving the highway landscape.

“…In overpass sections, retaining walls are often installed, and subway construction will not only affect road safety [1][2][3], but also threaten the stability and safety of the retaining walls. At present, there have been many studies on the stability of retaining walls, including the stability of retaining walls under static loads [4][5][6], the dynamic response of retaining walls [7][8][9][10][11], the behavior of retaining walls affected by deep excavation [12,13], and the time-dependent behavior of piles and retaining walls as a result of excavationinduced soil movement [14]. ese studies have made many achievements in terms of the stability of retaining walls.…”

Anzhen Bridge Station of Beijing metro line 12, which adopts a separated-island platform constructed by the undermining method, passes along the retaining wall of the North Third Ring Road. A numerical simulation method is adopted to study the deformation laws of the retaining wall under the influence of station construction. The simulation data show that the affected retaining wall will have large settlement and tilt, and countermeasures must be taken. Four countermeasures are formulated, and their control effects are analyzed. The calculation results show that the combination of anchor cables and waist beams can effectively control the tilt of the retaining wall, but the control effect on the absolute settlement is not obvious. The control effect of isolation piles is better than that of foundation grouting. The joint control method of anchor cables combined with waist beams, isolation piles, and deep hole grouting makes the deformation meet the target, and according to this measure, a concept of joint control aiming at the influence of the “source,” “propagation,” and “object” is proposed, which can provide a reference for similar projects with a great difficulty in deformation control.
