High-Mast Tower Foundation – Phase II
| 项目名称： | High-Mast Tower Foundation – Phase II |
| 摘要： | Phase I addressed a review of the research literature, design specifications, state of practice in electrical- and communication-tower embedment, and corrosion. A mastic layer is typically provided for corrosion protection. Next, the required resistance for a typical NDOT tower was computed with the developed tools. The foundation analysis and designs were conducted for sandy and clay soils typical of Nebraska with the resistance established. A finite element tool was developed for rigorous analysis, and this was combined with analysis from L-Pile, an industry standard. Finally, and significantly, site conditions and construction practices were documented. An appendix was developed that outlines project qualifications, execution methods, and construction documentation. Phase I work did not include testing. To our knowledge, no transportation structures have been directly embedded. The next step is to construct and test embedded poles in a controlled and safe location. NDOT property is suggested, but other sites may be possible. This project will: 1. Construct embedded poles 2. Statically test up to the design limit 3. Test the poles dynamically and monitor performance (low to high excitations applied with an eccentric mass oscillator (or shaker) – we will control the amplitude and loading frequency. We will monitor deformations, strains, and accelerations with our standard data acquisition and sensors. The number of cycles will approximate the years of service life. The proposed Phase II work will employ Phase I work with a construction demonstration followed by static and dynamic testing. Tools and methods developed in Phase I are directly applicable to Phase II. . |
