Deep Foundation Technologies for Infrastructure Development

加拿大目前面临着应对基础设施老化的巨大挑战，我国60%的公共基础设施已有40年以上的历史。这一关键基础设施得到具有相当大经济价值的不同类型基金会的支持。因此，迫切需要新的高效基础技术来支持新的基础设施，并升级和延长现有基础设施的寿命。拟议研究的主要目标是开发新的深基础系统和产品，将对环境的影响降至最低，并为建筑公司、该基础设施的所有者和运营商节省资金。这项研究计划将调查各种基础设施项目在各种环境和人为负载下的创新基础的表现。它将涉及被调查的基础系统的实地和实验测量，这将证明拟议的创新基础和产品的可行性和优越性能。此外，实验测量和观测将用于校准/验证分析和数值模型，这些模型可用于设计和评估被检查的基础技术的性能特征。拟议的研究计划包括三个研究方向，调查三种不同类型的基础设施的基础系统。这些研究方向涉及施工、分析和设计问题，包括不同的荷载条件、施工工艺和材料以及不同基础体系的反应特性。

Canada is currently facing enormous challenges dealing with the aging of infrastructures, with 60% of our public infrastructure is more than 40 years old. This critical infrastructure is supported by different types of foundations that are of considerable economic value. Hence, there is an urgent need for novel efficient foundation technologies to support new infrastructure and to upgrade and extend the life of existing infrastructure. The main objective of the proposed research is to develop novel deep foundation systems and products that will minimize environmental impact and will save money for construction companies, and owners and operators of this infrastructure. This research program will investigate the performance of innovative foundations for a variety of infrastructure projects subjected to a variety of environmental and man-made loadings. It will involve field and experimental measurements of investigated foundation systems, which will demonstrate the feasibility and superior performance of the proposed innovative foundations and products. In addition, the experimental measurements and observations will be used in calibrating/verifying analytical and numerical models that can be used for the design and evaluation of the performance characteristics of the examined foundation technologies.The proposed research program comprises three research directions that investigate foundation systems for three different types of infrastructure. These research directions deal with construction, analysis and design issues, including different loading conditions, construction techniques and materials, and response characteristics of different foundation systems.
