“…Most previous studies on retaining walls, such as stone walls [25,26], backfill soils [27], and reinforced earth retaining walls [28], have focused on horizontal loads, including soil pressure [29] and seismic forces [30]. Less attention has been given to vertical loads, such as vehicle-induced pressure on the wall's top [31]. In response to rising sea levels and increasingly frequent storm surges due to global warming, the ancient Qiantang River seawall is undergoing upgrade operations to increase its flood prevention standards.…”

Situated on the northern bank of the Qiantang River estuary, the ancient seawall serves not only as a national cultural relic but also as an active agent in flood and tide prevention. This seawall features a trapezoidal cross-section and is constructed with layered stone blocks and a sticky rice mortar. To investigate the load-bearing and deformation attributes of this ancient structure, a scaled-down specimen with a ratio of 1:4 was created. Monotonic and cyclic vertical loadings were then applied to the wall’s top surface. During these loading procedures, measurements of the loading force, seawall displacement, and front and side deformation fields were taken. Experimental findings reveal that the seawall tends to lean towards the soil-retaining side under vertical loading. After ten loading cycles, the vertical rigidity of the wall was reduced by 10%. Upon application of a uniformly distributed vertical load of 1.6 MPa at the top of the wall, significant cracks began to materialize in the blocks at the base of the seawall. When the loading at the top increased to 2 MPa, a vertical crack that cut through the mortar layer at the wall’s center was observed. By comparing it to a three-dimensional finite element model, the load-bearing and deformation characteristics of the ancient seawall observed in the experiments were confirmed, which could contribute to the scientifically informed conservation and protection of the seawall.

Three-dimensional finite element analysis has been carried out in order to study the response of retaining walls subjected to lateral earth pressure using ABAQUS/CAE. This study consists of analysis and design of cantilever, gravity type, and precast concrete retaining wall. It also shows comparative study such as distribution of stresses along with the deflection throughout the height of the retaining walls. The mathematical analysis procedure is adopted that entails selecting dimensions to meet the requirements of several codes and then evaluating the stability of the entire whenever the backfill load works on the wall. The stability of retaining walls in terms of sliding and overturning is evaluated. The three specified walls are then investigated using the ABAQUS software, and their behaviour is studied. In this analysis process, two components of the formed concrete wall; one is a base plate and another component is a cantilever sandwich panel, were projected. A headed anchor joins the prefabricated cantilever wall to the base plate, keeping the slab and wall together while also maintaining their integrity in the specific positions. The system requires a unique construction method for final assembly. Mainly two steps were followed for analysis: first, the different components for shear and bending moments, namely, heel and footplates, were designed, and then, the stability of the whole structure under load was evaluated. The ABAQUS program was used to simulate and analyse the stability of various walls, including traditional and precast concrete retaining walls. It was found on the basis of the observation that the prefabricated retaining wall is the most viable option out of the three as the stress and deflection in the former type are lowered.
