One of the most important problems of geotechnical engineering is the design of pile foundations. Piles are generally designed for vertical and horizontal static loads. However, it is important to design piles against dynamic loads in regions with high seismicity. This study verified a centrifuge experiment obtained from the literature with a finite element program. With the kinematic interaction analyses performed for this purpose, the effect of parameters such as layered soil, groundwater, pile stiffness, and earthquake acceleration were investigated numerically. According to the results obtained, it was understood that the earthquake magnitude is the most important parameter in kinematic interaction analyses. In addition, in layered soil conditions, the fact that 75% of the pile length is in the weak soil creates the most unfavorable situation. It was observed that pile stiffness and groundwater level also have certain effects on the kinematic interaction.

“…The results of the research are expected to help practitioners to plan the structure of the beach building, coastal protection, the structure of the building at sea, or marine structures. For example, as mentioned by Rathod et.al [15]; Piles used in marine structures are subjected to lateral loads from the impact of berthing ships and from waves. Piles used to support retaining walls, bridge piers and abutments, and machinery foundations carry combinations of vertical and horizontal loads.…”

SWAN (Simulating Wave Near-shore) is a numerical wave model for hindcasting/forecasting wave parameters in coastal areas. This numerical model is chosen because is suitable for shallow water. This study was conducted to verify the results of wave height hindcasting in Jepara coastal waters. This is expected to support wave characteristic research based on wave forecasting for 10 years in the waters between Java, Sumatera and Kalimantan. The model is run with the third-generation mode (GEN3), which allow wind input, quadruplet and triad interactions, whitecapping, and breaking. Wind data is obtained from ECMWF (European Centre for Medium-Range Weather Forecasts) and the bathymetry from GEBCO (General Bathymetric Chart of The Oceans). The validation of the model and buoy data during July -December 1993 shows a good result (Root Mean Square Error = 0.166 and correlation/ linear regression = 0.807). Based on the literature, qualitatively the model has been verified with other simulation from another model in the same location.

“…Pile foundations may not only subjected to static loads but also dynamic loads simultaneously. The study on the dynamic response of a single concrete pile in soft clay subjected to static and dynamic simultaneously has been presented [3]. The connection between pile to the cap also may be investigated to understand its behavior respected to the applied loads.…”

Additional Bearing Capacity of Piles Due to Time Delay of Injection

The use of long piles to support construction loads has been recognized for thousands of years. In the last century, it has been introduced the use of pressure for embedding pile foundations that is named injected piles. In field implementations, if the design depth of the piles is long enough then additional piles are required to be connected. It needs time delay to connect between the earlier embedded pile to the additional one. The time delay can be also caused by other things such as equipment problems, unwilling bad weather etc. Based on the experience of pile injection records, due to the time delay, there is a temporary increase in pile bearing capacity, so it takes more effort to continue pile penetrations until the specified depth. In this study, the effects of erection time delays on piles are investigated. This study is conducted using experimental injected-pile models at the laboratory. The initial depth of earlier piles prior to further injection is set the relatively same, while the time delays are varied. The injection loads for penetration are recorded as well as the depth of penetration. The results of the experiments in terms of variation of time delays and additional penetration loads show that there are 'jump loads' at the initial last depth due to time delay until a certain period. It can be concluded that the time delay on the pile can increase the bearing capacity and must be limited to a certain time in case of pile connection work on site. The variation additional loads due to the time delays in a soil mass may be affected by soil parameters such as density and particle size of the soil.
