Development of Full Scale Testing of an Alternate Foundation System for Post and Panel Retaining Walls

摘要

The alternate post system offers benefits such as ease of construction, reduced construction time, and lower wall costs. While this system seems feasible, there are concerns regarding its performance, in particular the amount of bending in the post and the defection of the wall due to active earth pressures exerted by the retained soil. Other concerns include the potential damage to the plate during driving, control and accuracy of post alignment, and long term issues such as corrosion and soil creep. The objective of this research project is to assess the feasibility of the alternate post system. If the system is deemed feasible, the research team will develop design criteria for the alternate post system based on exposed wall heights, applied soil loads, post dimensions, and parameters of the retained soil and the foundation soil.
