Bearing Capacity Factors for Shallow Foundations Subject to Combined Lateral and Axial Loading
| 项目名称： | Bearing Capacity Factors for Shallow Foundations Subject to Combined Lateral and Axial Loading |
| 摘要： | The objectives of this project are to: (1) Collect Data on current B/L (width/length), embedment (D/B), eccentricity, lateral/axial load combination and sand densities beneath shallow foundations in Florida. (2) Select 1 average foundation width, B 2 B/L rations, 2 embedment depths, 2 loading locations, 3.5 axial to lateral load ration, and 2 sand densities for centrifuge testing. (3) Based on the results of the first 112 tests, 3 conditions will be repeated where D near B. (4) Construct a loading frame fro shallow foundation testing in the centrifuge which considers, 2 embedment depths, 2 load locations on the foundation with 3.5 axial/lateral load ratios, (5) Conduct all of the centrifuge tests with various soil densities, axial/lateral load ratios to obtain both the measure nominal bearing capacity as well as the measured axial/lateral inclination and eccentricity factors. (6) Compare the measured centrifuge results with current American Association of State Highway and Transportation Officials (AASHTO) bearing equations as well as European and Australian approaches, and identify which combination of bearing combination factors are representative/recommended for Florida Department of Transportation (FDOT) use. |
