preventing reoccurrence of catastrophic failures of stormwater pipelines

该项目旨在开发一种技术来准确预测劣化的埋地雨水管道的剩余安全寿命，从而防止其灾难性的失效。研究还旨在增进对钢筋混凝土劣化科学和埋地管道破坏理论的认识。预计结果将是一套合理的、实用的和经过验证的管道劣化模型，通过裂纹扩展和剩余强度来衡量，这些模型被集成到与时间相关的可靠性方法中，并编码为计算机程序，供最终用户使用。防止埋地管道的灾难性故障应能带来经济、环境和社会效益。

This project aims to develop a technique to accurately predict the remaining safe life of deteriorated buried stormwater pipelines, thereby preventing their catastrophic failure. The research also aims to advance knowledge in deterioration science of reinforced concrete and failure theory of buried pipes. The outcomes are anticipated to be a suite of rational, practical and validated models for pipe deterioration as measured by crack growth and residual strength which are integrated in a time-dependent reliability method and coded as a computer program ready for take-up by end-users. Preventing catastrophic failures of buried pipes should deliver economic, environmental and social benefits.
