VIBRATIONS INDUCED BY CONSTRUCTION .

In the United States, there have been a limited number of studies done on non-blasting construction activities producing damaging vibrations, namely construction traffic. In many cases, various state and federal agencies have adopted empirical limits, in terms of peak particle velocity (PPV), in an effort to limit construction vibrations. Due to either the frequency of the ground motion or the ...
