Post Foundations for Flexible Rockfall Fences

This paper will discuss how the use of flexible rock nets to protect transportation infrastructure is gaining popularity with departments of transportation (DOT’s) throughout the United States. As more of these structures are constructed and impacted by rockfall, design procedures and construction methods are adapting to more accurately and efficiently predict and resist the loads imparted to the structure via dynamic impacts from rockfall. This research paper will examine the design and construction of post foundations for flexible rock nets. Topics will include: (1) current industry standards for the design and construction of post assemblies and post foundations for flexible rock nets; (2) shear and axial demands and resistances of post assemblies and foundations; and (3) effects of dynamic loading on the passive and shear resistance of varying foundation soil and rock types. The objective of this paper is to begin development of uniform standards for the design of post foundations for flexible rock nets, which will ensure the structural integrity and cost effectiveness of structures to be constructed in the future.
