Failure analyses of open-ended pre-stressed high-strength concrete pile during driving: insights from distributed fiber optic sensing
Open-ended pre-stressed high-strength concrete (PHC) pipe piles are susceptible to progressive distortion and even failure in the vicinity of the pile toe during driving into stiff soil or rock strata. This pa...
