Failure Investigation of Olympic-Sized Swimming Pool

摘要

From the beginning of the operation of the Olympic Pool in Tennessee, there were signs of trouble, such as liner bubbles, cloudy water, differential gutter rim level, sand in the bottom of the pool, and dirty filter bags. After eight months of operation, sand could be seen coming out of the inlets and one blister, located approximately in the middle of the pool rose above the water and finally the pool liner tore. In determining the causes of the problem, the subgrade subsidence, pool wall settlement and distortion, and sub-floor pipe damage were considered in this investigation. Laboratory testing and subsurface investigations were performed In this investigation, the mechanism of the failure and the reasons behind the liner bubble were explored and discussed. As described in the paper, it appears that significant fracturing of the sub-floor plumbing due to compression of under-compacted fill caused pipe failure. Knowing the mechanism of the failure helped to sustain the pool and keep it operational.
