Compaction‐Induced Earth Pressures Under K0‐Conditions

Abstract

Analytical models and procedures are presented for the evaluation of peak and residual compaction‐induced lateral earth pressures either in the free field or adjacent to vertical, nondeflecting soil‐structure interfaces. A hysteretic model for the stresses generated by multiple cycles of loading and unloading is presented, along with recommendations regarding the determination of suitable model parameters. This model is then adapted to incremental analytical methods for the evaluation of peak and residual earth pressures resulting from the placement and compaction of soil. Compaction loading is considered as a transient moving surficial load of finite lateral extent. Simplified hand calculation procedures are presented for cases in which all soil layers are identically compacted. Finally, a series of case studies are presented in which analytical results are compared with full‐scale field measurements in order to verify these analytical methods.
