The high computational costs associated with the implicit formulation of discontinuous deformation analysis (DDA) have been one of the major obstacles for its implementation to engineering problems involving jointed rock masses with large numbers of blocks. In this paper, the Newmark‐based predictor‐corrector solution (NPC) approach was modified to improve the performance of the original DDA solution...
Micropiles are small-diameter piles installed in soil. Due to wide application of micropiles in seismically active areas, investigation of their behavior during earthquake is of great significance. In this study, shaking table tests were conducted on a small-scale physical model of micropiles consisting 16 vertical micropiles embedded in loose sand fill and subjected to harmonic sine waves. Influence...
