Experimental and Theoretical Evaluation of Pile Bearing Capacity Utilizing the All-Pile Program

Abstract

The number and distribution of piles are considered to be significantly influenced by the estimation of pile bearing capacity, which is depending on the results of an on-site loading test. Based on the soil properties determined through laboratory and field experiments, the load-settlement relationship for different piles was calculated using the All-Pile program in this investigation. Additionally, it was employed to assess the bearing capacity of the piles by comparing theoretical and practical outcomes according to a variety of criteria. According to the outcomes of field tests and an analysis of the load subsidence relationship derived from soil investigations, it was determined that the program is capable of estimating the bearing capacity of piles for various types and values, accordingly determining the bearing capacity of the piles. Considering the research findings that the study presents, the theoretical method (All pile program) results of bearing capacity are about 15% higher than practical bearing capacity of Pile Load Test result and the theoretical results could be used to predict the practical ultimate bearing capacity according to the relation between the theoretical and practical results observed in the present study. When the piles lengthen from 25 to 45 meters, the ultimate bearing capacity of the practical results increases by roughly 35%, while for theocratic results increase about 21%.
