Piles driven in sand are very commonly used to support structures in Australia. Their design, however, is based on pile capacities measured shortly after installation - even though capacities are observed to increase significantly with time. This proposal seeks to develop a methodology through which the effects of time can be incorporated in design and hence lead to cheaper foundation solutions.

在澳大利亚，在砂中打入的桩通常用于支撑结构。然而，它们的设计是基于安装后不久测量的桩承载力-即使观察到承载力随时间显著增加。该提案旨在开发一种方法，通过该方法，可以将时间的影响纳入设计，从而导致更便宜的基础解决方案。
