POTENTIAL APPLICATION OF SEISMIC AND ACOUSTIC EMISSION/MICROSEISMIC TECHNIQUES TO THE MONITORING OF HIGHWAY SUBSIDENCE. FINAL REPORT

This 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. This report summarizes the findings of the airport study and discusses the unique aspects of highway subsidence monitoring. A methodology to locate and monitor shallow cavities is contained within the report. A more detailed report is published under the title, "A Study to Monitor Microseismic Activity to Detect Sinkholes," by Hardy, et al., 1986. It is also available through NTIS.
