Ground surface explosion experiments were conducted on a double-box utility tunnel buried
in calcareous sand to study the structural dynamic responses and damage characteristics …

Surface explosion tests were conducted on calcareous sands to study the ground shock
propagation in this medium. In the tests, ground shock at scaled distances between 0.33 …

Coral sand is characterized by high porosity, high compressibility and high crushability
mainly due to its irregular particle shape and internal pore structure. Single coral particles in …

To simultaneously improve the strength, deformability, and durability of coral aggregate
concrete (CAC), a systematic strengthening program of coral coarse aggregate (CCA) was …

Full understanding of dynamic mechanical characteristics of coal samples under true triaxial
condition is of great significance for preventing and controlling deep coal and rock dynamic …

The motion of particle clouds (ie, sediment clouds) usually can be found in engineering
applications such as wastewater discharge, land reclamation, and marine bed capping. In …

Abstract The three-dimensional (3D) stress waves of coal samples were studied using a true
triaxial split Hopkinson pressure bar compression rod. The results indicate that the 3D strain …

Abstract Tire-derived Aggregate (TDA), as a recycled material, has shown great potentials in
enhancing the mechanical and durability behaviors of railway ballast. In addition, economic …

为研究应变率对珊瑚砂力学特性的影响, 用直径37 mm 的分离式Hopkinson 压杆(SHPB)
对两类珊瑚砂进行了冲击实验, 得到了460~ 1 300 s− 1 应变率范围内不同密实度的一维应变 …

Abstract The Split Hopkinson Pressure Bar (SHPB) is the common testing method used to
investigate the high strain rates behavior of engineering materials. In this paper, a …
