Bearing capacity of pile accuracy results obtained from dynamic measurements using PDA

Dynamic tester using candles) PDA, now constitutes a new method in the estimation of pile cargo capacity is used. Currently, compliance information chart force - time calculated with the data registered and selected variables, soil resistance, using the complementary software) CAPWAP}, to obtain the experimental process is pile cargo capacity. Therefore, considering the nature of trial and error in the algorithm programs and diversity in the number of variables affecting soil CAPWAP during the process of obtaining the best match of the uses may be selected variables to the index matching identical results Bearing capacity varies achieved. In the first part has been trying to change the amount of soil variables and its effect on the distribution of cargo capacity between the wall and pile tip and overall cargo capacity, to achieve a similar adaptation index for a specific measure, they review. Also continuing on the reliability analysis of samples has been studied. In this analysis using the design load and resistance coefficients and considering the results of both static and dynamic analysis on Nmvnhyy given a reliability index versus rupture time obtained from static analysis results and effect change on the PDA reliability index calculation and design safety level has been investigated.
