摘要

This study investigates the application of Settlement Reduction Micropiles (SRMPs) to stabilize differential settlement in the 501B sulfuric acid storage tank at the Kerman copper industrial complex. The tank experienced 32 mm of differential settlement and rigid-body tilting due to subsurface void collapse beneath the foundation. A three-dimensional finite element model was developed to evaluate intentionally weak micropiles designed to control progressive differential settlement rather than eliminate total settlement. The model was validated using full-scale micropile compression tests and staged deformation surveys conducted during retrofitting. Numerical results indicated that, without improvement, differential settlement could increase to about 40 mm, causing non-uniform load redistribution and higher serviceability risk. Field monitoring confirmed that the installed SRMP system effectively arrested further differential settlement and maintained nearly uniform deformation under operational loading. Settlement of fixed monitoring points ranged from 8 to 10 mm across the tank roof four months after loading. Given the hazardous nature of stored sulfuric acid, controlling foundation tilting is essential to prevent leakage, structural distress, and environmental contamination. The SRMP technique proved to be a minimally invasive and cost-effective retrofit solution that improves serviceability by stabilizing differential settlement in large industrial storage tanks.
