“…It is difficult to perceive the ultimate bearing capacity intuitively from such curves. For this scenario, many interpretation methods based on graphical construction, mathematical model and settlement limit have been proposed [5][6][7].…”

Determining the ultimate bearing capacity of pile is important for reasonable design of the pile. In this paper, a cusp catastrophe theory-based method was proposed for assessing the ultimate bearing capacity of static loading pile. Firstly, a three-parameter quartic polynomial in accordance with the standard form of cusp catastrophe model is proposed and used to fit the experimentally obtained Q–S curve. The parameters which allow the polynomial to produce best fitting to the Q–S curve are taken to identify the stability of the pile following a simple procedure. Then, the proposed method was verified against 10 Q–S curves obtained from field tests at Jinqiao-Meiya and Jinqiao-Chunyu areas of Shanghai. Results show that the ultimate bearing capacities of the piles identified by the proposed method were comparable to those identified by the JGJ 106-2014 standard method. Finally, it is found that the stability of the pile identified by the proposed method and the mechanical state of the pile identified by the Golden Section approach were correlated closely.

“…The force condition of piles during static pile sinking has been extensively studied over the years utilizing theoretical analysis, field measurements, indoor experiments, and numerical simulations, and various research findings have been attained. [3][4][5][6][7][8][9][10][11][12][13][14]. In terms of theoretical analysis, Jingpei Li et al [3] enhanced the Cambridge model by computing the pile side resistance and end resistance using the column bore expansion theory and the SMP criterion-based spherical bore expansion theory, fully validating their results with examples.…”

“…They obtained a single curve of the end-bearing response. A new technique for installing piles called the Jacking and Rotary method was presented by Hassan Nor Syamira et al [11], to determine the behavior of piles tested by static load and compared with their test results by the common method, which is Jacking (J). The findings demonstrate that the J&R method may be used to lay pile foundations, ensuring its use in engineering practice.…”

Model tests are carried out on the jacked single piles of different diameters and pile lengths under the model pile of different diameters and pile lengths in clayey soil, which aims to investigate the penetration mechanical mechanism. How to accurately test the pile end resistance and pile side resistance during jacked pile sinking is particularly important. In this paper, a full-section spoke-type pressure sensor, a double diaphragm temperature self-compensating fiber Bragg grating (FBG) earth pressure sensor and a sensitized miniature FBG strain sensor are jointly applied to a single pile penetration model test to test a single pile driving force, pile end resistance and pile body stress during penetration. The test results show that the load transfer performance of test piles will be affected by different diameters, and the axial force transfer capability of a large diameter in the depth direction is better than that of a small diameter since the compacting effect is more obvious. The unit skin friction of the pile increases gradually as the depth increases, which is larger due to the lateral extrusion force increasing as the diameter increases. At the same depth, the unit skin friction of two different diameter piles demonstrates “friction fatigue”, which also decreases obviously as the depth increases. Under the conditions of this test, the maximum frictional resistance of the pile TP1 pile side is about 27.7% higher than that of the test pile TP2. In the static pile sinking process of three test piles in cohesive soil, 50% is end bearing; therefore, there is 50% friction, and the diameter influences the end bearing and the length influences the friction.
