中文摘要
澳大利亚的沿海土壤往往对铁路的设计和建设构成重大挑战。该项目旨在开发一种新型的管桩和预制垂直排水管混合系统,以防止软基土壤(路基)在重载列车长时间循环荷载下过度屈服。利用大规模的物理模型模拟和现场试验支持的土壤桩排水相互作用机制的数值分析,这一创新的概念将被检查,以建立一个用户友好的设计方法。对于铁路运营商来说,这些成果将大幅降低维护成本,同时延长轨道基础设施的寿命,以确保未来更快、更重的列车。
英文摘要
Australian coastal soils often pose significant challenges in the design and construction of railways. The project aims to develop a novel hybrid system of pipe piles & prefabricated vertical drains installed to prevent soft foundation soil (subgrade) from excessive yielding under prolonged cyclic loading by heavy-haul trains. Using large-scale physical model simulations and field trials supported by numerical analysis of soil-pile-drain interaction mechanisms, this innovative concept will be examined to establish a user-friendly design methodology. For rail operators, the outcomes will generate substantially reduced maintenance costs, while extending the longevity of track infrastructure to ensure faster and heavier trains of the future.
