دانلود مقاله Improving dynamic soil parameters and advancing the pile signal matching technique 20

چکیده : 

The pile signal matching technique widely used for estimating vertical resistances of piles during construction

is highly influenced by the assumed dynamic soil parameters. Due to the lack of understanding

and supporting data, constant soil parameters for the entire pile length have been routinely used. This

practice is unrealistic and compromises the signal match quality. Using recently completed field tests,

this paper develops empirical equations for dynamic soil parameters in terms of measureable soil properties

and proposes an improved signal matching technique, thereby allowing for better match quality
