TL;DR: In this article, the authors investigated the train-induced settlement of a metro tunnel in saturated clay through the soil-water full coupling dynamic finite element method (FEM), where the train vibration load was first evaluated using the rail-fastener-tunnel-subgrade model and then applied to the track bed to simulate the movement of metro train in the 3D model.

TL;DR: In this article, a series of laboratory experiments were conducted to evaluate the correlation between depositional environment, chemical and mechanical properties of marine clays, which can provide valuable references for investigating the engineering properties of soft clays.

TL;DR: In this article, a sophisticated model-based numerical simulation, using a soil-water coupled finite element (FE)-finite difference (FD) hybrid algorithm, is conducted to investigate the mechanism of the settlement of the piled-raft foundation and excess pore water pressure (EPWP) of soft soils caused by the cyclic train loading.

TL;DR: In this paper, a ground treatment technique was proposed to reduce permanent train-induced deformation in soft clay ground for high-speed trains has suffered serious settlement due to cyclic train loading in recent years.

TL;DR: In this article, a series of multi-step creep tests are conducted, and a method for predicting the accelerating creep stage is proposed, based on the relationship between the starting point creep deformation and the shear creep stress.
