Abstract: 

DYNAMIC TESTING OF PILE USING PILE DRIVING ANALYZER HAS BECOME MODERN SOLUTION TO ESTIMATE PILE BEARING CAPACITY. AT THE PRESENT TIME, TO CALCULATE SUCH A CAPACITY, THE MATCH OF TIME-ENERGY FIGURE DATA THAT HAS BEEN DERIVED FROM RECORDED INFORMATION AND THE SELECTION OF OIL RESISTANCE VARIABLES USING COMPLEMENTARY SOFTWARE, CAPWAP, ARE MATTERS OF EXPERIMENT. THEREFORE, CONSIDERING THE TEST AND ERROR IN THE ALGORITHM AND THE EXISTENCE OF GREAT VARIETY OF VARIABLES THAT AFFECT SOIL WHICH IS USED BY CAPWAP IN ITS PROCESS TO ACHIEVE THE BEST MATCH, IT IS POSSIBLE TO ACHIEVE A MATCH QUALITY THAT CORRESPONDS TO THE RESULTS ALREADY ACHIEVED ABOUT PILE BEARING CAPACITY. THIS ARTICLE INTENDS TO STUDY THE IMPACT OF ALTERATIONS IN SOIL PARAMETERS AND CONSIDER SUCH EFFECTS ON THE BEARING CAPACITY DISTRIBUTED BETWEEN PILE TIP AND PILE WALL AND TOTALLY ON BEARING CAPACITY IN ORDER TO ACHIEVE A MATCH QUALITY THAT IS SIMILAR TO A PARTICULAR RECORD. FROM AMONG THE TOTAL NUMBER OF 12 SAMPLES WHICH ARE CONSIDERED TO BE SUITABLE FOR ACHIEVING MATCH QUALITY, 6 VARIABLES ARE CASE DAMPING FOR THE TIP AND WALL OF THE PILE. SMITH DAMPING IS OF GREAT IMPORTANCE FOR WALL AND TIP OF THE PILE AS WELL AS MAXIMAL QUAKE DISPLACEMENT.

Abstract: 

In recent years determining bearing capacity of piles from in-situ testing data as a complement of static and dynamic analysis has been used by geotechnical engineers. In this paper, different approaches for estimating the bearing capacity of piles from SPT data have been explained and compared. A new method based on the N-value from SPT is presented and calibrated. Data averaging, failure zone extension, and plunging failure of piles has been noticed in the proposed approach. A data base has been compiled including 43 full scale static pile load tests and 17 dynamic testings which were analyzed with the signal matching technique by CAPWAP. The SPT data were performed close to pile locations are also included in the data base. A comparison of current methods by error investigation with cumulative probability and Log-Normal approaches demonstrates that the proposed method predicts pile capacity with more accuracy and less scatter than other methods. Results of prediction with good agreement to measured capacities indicate that the proposed method can be used as an alternative for determining the bearing capacity of piles in geotechnical practice.
