Probabilistic Liquefaction and Lateral Spread Hazard Mapping for Utah County
| 项目名称： | Probabilistic Liquefaction and Lateral Spread Hazard Mapping for Utah County |
| 摘要： | This project is a continuation of the recent research efforts initiated by the University of Utah to apply an innovative probabilistic approach to develop modernized hazard maps of liquefaction triggering and lateral spread displacement for the Wasatch Front in Utah, including Salt Lake, Davis, Weber, Utah, and Cache Counties. Utah County is the state’s second most populated county, and it is known to have substantial liquefaction and lateral spread hazard due to its proximity to Utah Lake (i.e. very high groundwater), the greater amount of sand and silt in the soil, and relatively steep topography. The development of probabilistic liquefaction and lateral spread hazard maps will provide an important risk assessment tool to those agencies, departments, and industries who have recently invested their time and money in Utah County. State departments like Utah Department of Transportation (UDOT) could use the hazard maps to evaluate their transportation network and to identify potential “problem spots” where future liquefaction mitigation work might be a good idea. Furthermore, probabilistic hazard maps are an invaluable tool when performing emergency/disaster scenario and impact studies. The objectives for this study include: (1) development of a comprehensive geotechnical database consisting of soil borings (i.e., standard penetration tests), cone penetration test soundings, shear wave velocity profiles, and soil engineering properties; and (2) utilizing the developed database and available geologic maps, develop probabilistic maps for liquefaction triggering and lateral spread displacement hazard in Utah County. |
