Discrete Element Modeling of Instability Mechanisms of Unbound Permeable Aggregate Base Materials in Triaxial Compression

Discrete Element Modeling of Instability Mechanisms of Unbound Permeable Aggregate Base Materials in Triaxial Compression

Unbound permeable aggregate base (UPAB) materials with strong load‐transmitting skeleton yet adequate inter‐connected pores are desired for use in the sponge‐city initiative. However, the micro‐scale fabric evolution and instability mechanism of macroscopic strength behavior of such UPAB materials s...
