Summary: Fast heavy haul operations impart repeated (cyclic) loads on the natural formation that can fluidise (mud pumping), if the build-up of pore water pressure becomes excessive, causing track failure. This project aims toexamine the factors that govern mud pumping and evaluate the effectiveness of sub-surface drainage to preventtrack instability. Through a systematic experimental program and field study, the mechanisms of mud pumpingincorporating train loads and frequencies will be studied, and the role of vertically installed drains will be quantifiedfor improved practical design. The research outcomes will contribute to improved track longevity and reducedmaintenance costs, with a corresponding boost in rail productivity.
