The pile-anchor supporting structure is widely used in foundation pit engineering; then knowledge of active earth pressure on piles very important for engineers. In this paper, based the pseudodynamic method and considering vehicle’s vibration characteristic, a to calculate under vehicle load presented. At same time, constraint anchor simplified relation lateral deformation present method. Effects wide range parameters like rupture angle, acceleration coefficient, wall friction soil angle...
To reduce the impact of mountain rockfall on shed tunnel, cushion buffering materials were designed as protective measures. The optimized design can improve energy effectively dissipation. In present study, numerical simulation dynamics three granular (spherical, cylindrical and square) was investigated by discrete element method. Particularly, mesoscale respectively discussed how particle shape V0 (initial velocity) affect pressure; kinetic energy; friction mobilization; force chain...

Mountain bridges and highways frequently implement shed structures to guard against rolling stone disasters. Due the random variable nature of angle at which stones impact sheds, bedding material is often easily displaced, leading a wider range potential damages. In this paper, we analyze effectiveness varying grades when struck by different angles. We also examine mechanism microscopic force chains involved in process through use numerical simulations physical testing.In simulation tests...

As one of the most common geological disasters, rockfalls seriously threaten safety linear projects such as roads, railways, and oil natural gas pipelines. The rigid protective structures that are used for disaster reduction easily damaged by impact rockfalls, which affects service life structures. Consequently, buffer layer has been introduced to resolve this problem. In work, numerical simulations were carried out discrete element method study interaction between falling rocks granular...
