Dynamic Characteristics of Geogrid-Reinforced Foamed Lightweight Soil Under Cyclic Loading

Buildings
Although foamed lightweight soil is widely used for its light weight and high strength, its insufficient dynamic performance under cyclic loading and the poorly understood reinforcement mechanism have become key bottlenecks restricting its optimized ...
