“…One of the methods of Mazurkiewicz (1972) assumes that the greatest resistance capacity (ultimate) will be obtained from intersecting loads, including loads that are in the direction of the pole axis for connected load with points from the position of the line to an angle of 45° on the axis load bordering the load. The procedure for determining the ultimate load using this method is as follows [12]:…”

This study focused on the effect of trapped water on the bearing capacity of PVC pipe pile foundations. This research is divided into two models. The first model (pressure cap pipe pole) and the second model (open press pipe pole) each consist of four variations of PVC pipe diameters of 5.08 cm, 6.35 cm, 7.62 cm, and 10.16 cm (standard size PVC pipe diameter) with the same length of 30 cm. In the first type, all pipes are tightly closed at their upper ends. In the second type, all upper-end caps are given two holes, each with a diameter of 0.5 cm. Each pipe pile is alternately piled into soft soil with a moisture content of 98.8% is in a glass box measuring 120 cm x 20 cm x 60 cm. The test results of the load against decrease were analyzed using the Mazurkiwicks interpretation method. The bearing capacity of the end of the pole (Qp) along with the air trapped in the pipe pile (QA) can increase the carrying capacity of important poles compared to the carrying capacity of the pole side (Qs). PVC pipe poles belong to the floating pile foundation group due to the influence of air trapped inside the pile.

“…Also, the pile loading test result was analyzed using the finite element method based on the results of empirical methods and interpretation of the ultimate bearing capacity of the field test. The results of this study showed the finite element approach, Luciono Decourt, and Lastiasih are the closest to producing ultimate bearing capacity using loading pile tests at failure [18]. The data from pile load tests for three different regions in Nasiriyah, southern Iraq was used to determine pile capacity by adopting various interpreting methodologies.…”

The pile’s ultimate capacity or failure load must be computed by some criteria using load-settlement curve data gathered during the pile load test. Many scholars have proposed several approaches for evaluating the pile’s ultimate capacity in the past. This study compared different failure criteria to predict the ultimate load capacity for piles with two different lengths-to-diameter ratios embedded in gypseous soil with gypsum content of 60% under soaked and unsoaked conditions. Two types of piles were used. Floating pile and end-bearing pile. Davisson, Brinch Hansen’s 80 percent, Chin-Kondner, Mazurkiewicz’s, and Brinch Hansen’s 90 methods that were used in this study predict a higher value of the ultimate pile capacity, whereas the Decourt Extrapolation method gave fluctuated value. Fuller and Hoy’s, Butler and Hoy’s methods give far away value from realistic. On the other hand, Shen’s, ASTM, Terzaghi, and DeBeer’s methods predicted an acceptable and realistic value. The failure criterion of (15%D) where (D) is pile diameter according to(ASTM D-1143) was adopted in this type of soil.

“…In the second part of the study, the Ozkan-Alku method was developed [24]. In another study, the results of five different pile loading tests carried out in various parts of the Jakarta region were examined with different methods [27]. The method closest to the results of the pile loading test was found to be the Lastiasih and Sidi methods [28].…”

“…In another study, the results of 22 pile loading tests in three different areas of Nasiriyah were evaluated with analytical methods [35]. Accordingly, Chin-Kondner and Hansen were the methods that gave the highest failure load [21][22][23][24][25][26][27][28][29][30][31][32]. The Decourt, De Beer, and Mazurkiewicz methods gave the closest mean values to the failure load [5,22,26].…”

Determining the ultimate bearing capacity of piled foundations has been one of the most important problems in geotechnical engineering. It has been observed that the pile loading test evaluation methods based on the mathematical model give values far away from the failure load, even in piles that have reached the failure state. For this reason, it is aimed at developing a new mathematical pile loading test evaluation method based on the load-settlement curve. It has been thought that the main problem with the pile loading test evaluation methods based on other mathematical models giving values far from the failure load is that the methods iterate excessively. The new method proposed in the study was developed by taking this situation into account. The performance of the proposed new method was investigated using eight pile loading tests conducted in various provinces of Turkey. In order to verify the reliability of the newly developed method, the study was completed by applying multiple comparison tests with other methods in the literature (theoretical methods, finite element analysis methods, and pile loading test evaluation methods). According to the applied analysis of variance, it was concluded that the proposed new method remained within the 95% confidence interval and was usable.
