Correlation analyses of dynamic and static loading tests for nine piles

摘要

Can the accuracy of dynamic pile testing meet the demands of engineering? Engineers are always concerned with this problem as well as fall into arguments on it. In this paper, the correlation results of dynamic and static loading tests for nine prestressed-concrete pipe piles are studied. The two testing methods are compared in three aspects including the capacity, the settlement ratio and the load-movement curve. In addition, causes of diversity are discussed. As a tool for the acceptance test, the dynamic testing method is evaluated based on comparisons and analyses.
