Ground Vibration & Blast MonitoringVibration and blast monitoring is conducted where ground vibration as a result of construction or mining activities may cause damage to nearby existing structures. Such construction activities may include deep dynamic compaction of soils, pile driving, or general construction activities. This technique monitors the energy resulting from construction or blast activities as expressed in units of soil peak particle velocity. This allows a comparison with known threshold levels above which damage to structures is known to occur. The survey includes recording field data with a specialized digital seismograph and geophone and recording field notes detailing the events that may correspond to the construction or mining activity. These survey results are utilized to evaluate whether or not damage to nearby structures was caused by the observed ground vibration energy levels associated with the construction or mining activity. |
State Route 51 HOV LanesNinyo & Moore performed geophysical and geotechnical evaluations for the design of the highway-to-highway transition between Interstate 10 and State Route 51 and the addition of High Occupancy Vehicle Lanes on State Route 51 from Interstate 10 to Shea Boulevard. Ninyo & Moore used geophysical digital recording seismographs and monitored ground vibrations prior to and during... |
