Influence of Spatial Variability on the Design and Performance of Pile Foundations

目前，还没有将土壤性质的空间变异性纳入桩基设计和分析的模型。此外，只有基本的经验法则可用于协助确定桩的适当现场调查范围，并且可用于桩的LRFD的数据有限。新的、独特的有限元模型、现场勘察指南和荷载抗力因素将减少与桩设计相关的过度设计和不确定性，从而使桩基础更加可靠，减少建设成本超支和延误。保守地估计，仅在澳大利亚，这项研究每年将节省1 000多万美元。

Currently, no model is available that incorporates the spatial variability of soil properties into the design and analysis of pile foundations. Furthermore, only basic rules-of-thumb are available to assist in determining the scope of appropriate site investigations for piles, and limited data are available for the LRFD of piles. The new and unique finite element model, site investigation guidelines and load resistance factors will reduce the over-design and uncertainty associated with pile design, which will lead to more reliable pile foundations and reduced construction cost overruns and delays. Conservatively, it is estimated that this research will result in savings in excess of $10 million per year, in Australia alone.
