Accumulated Deformation Behavior and Computational Model of Water-Rich Mudstone Under Cyclic Loading

With the rapid development of Chinese railway systems, a large number of railway tracks have been built on or across soft soils and soft rocks, resulting in problems such as accumulated deformation and settlements of the tracks (Zhang et al. 2009) and severe mud pumping in railway tunnels which are...

Description
Summary:With the rapid development of Chinese railway systems, a large number of railway tracks have been built on or across soft soils and soft rocks, resulting in problems such as accumulated deformation and settlements of the tracks (Zhang et al. 2009) and severe mud pumping in railway tunnels which are built through soft soils (Zhu and Li 2001). Such problems are a big challenge to the safety and efciency of train operation. Investigations on the characteristics of long-term deformation of geotechnical materials under cyclic train loading are of great interest in engineering practice. Sangrey and Henkel (1969) conducted triaxial cycling tests for saturated soft clay and demonstrated the existence of a critical stress state for soils.
