Jackson South Snow Supporting Structures Proposed Performance and Health Monitoring of WYDOT Project No. N104085, Teton County, Jackson Wyoming

The purpose of this project is to evaluate the performance of the milepost 151 snow supporting structure (SSS) installation, and will also provide an initial base for development of design guidelines for future constructed snow defense measures at other locations within the western United States. The project will also verify design parameters and establish domestic guidance documents. This project will provide valuable information on the active snow pressures and in-situ performance of the SSS at milepost 151 site near Jackson, Wyoming. Vibrating wire strain gauges, sensors and snow temperature meters, and snow depth sensors will be installed on two (2) SSS. The instrumentation will be used to monitor both structural parameters and meteorological conditions over two (2) winter seasons. The internal structure force efforts combined with measured meteorological data will be used to back analyze the active snow load pressures imparted to the structures. The back-analysis active snow pressures will be compared to those predicted using existing European methods, which are a function of slope angle, aspect, and ground surface conditions, snow density, structure spacing and structure geometry. During each summer of the project, the SSS will be visually observed to document the visual structural health. The results developed in this project will be used to evaluate the performance of the milepost 151 installation and will also provide an initial basis for development of design guidelines for future constructed defense measures at other locations within the western United States.
