Assessing the Long-Term Performance of Mechanically Stabilized Earth Walls. A Synthesis of Highway Practice.

摘要

Mechanically stabilized earth (MSE) walls are retaining walls that rely on internal reinforcement embedded in the backfill for stability. This study addresses methods currently used to assess long-term performance of MSE walls, where long-term denotes the period of time from approximately one year after the wall is in service until the end of its design life. The focus of the study is on state and federal agency wall inventories, including methods of inspection and assessment of wall conditions. Information was gathered through a literature review, agency survey, and selected interviews. Travis M. Gerber, URS Corporation, Salt Lake City, Utah, collected and synthesized the information and wrote the report. The members of the topic panel are acknowledged on the preceding page. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand.
