Potential Application of Seismic and Acoustic Emission/Microseismic Techniques to the Monitoring of Highway Subsidence

摘要

The report discusses the problem of highway subsidence and considers the possible application of seismic and acoustic emission/microseismic (AE/MS) techniques for monitoring such subsidence. Reference is made to the results of a recent sinkhole-monitoring study undertaken at Capital City Airport, New Cumberland, Pennsylvania. These results are considered to be directly relevant to the problem of karst or mining-induced highway subsidence. The report summarizes the findings of the airport study and discusses the unique aspects of highway subsidence monitoring.
