Abstract

The Tennessee Central Foothills Parkway is a 16-mile span of scenic highway that winds around the Smokey Mountains. The project was approved by congress in 1944 and remains incomplete, making it the nation’s longest undergoing construction project. Its original approval was tied to the WPA program and was recently restarted as a shovel ready project under the 2009 ARRA initiative. The goal of this research project is to monitor the load transfer and moment distribution in the micro piles used to support the two largest piers of Bridge No. 2 on this steep terrain. The piers are supported on 20-micropiles of (~95-ft length) and tied together by a five-ft thick pile cap. In addition to the superstructure load transfer on the bond zone into rock, the effects of grout hydration on the instrumentation installed in the micro piles were studied. A laboratory sample of the micro pile’s cross section was prepared and monitored to observe possible stresses induced during the hydration of the grout. Results are currently being analyzed.
