This paper presents the results of a series of numerical analysis carried out on piles in cohesive soils. Broms (1964a) proposed graphs to obtain ultimate lateral bearing capacity of such piles. However, the graphs do not cover all piles with different lengths. In this study, a finite difference program that is especially designed for piles is used. The investigations were carried out by varyin...

Model tests were carried out in dry silica sand under pile loading and visualizing observation to investigate the behavior of a pile group. The pile group consisted of nine cylindrical model piles of 40 mm in diameter in most tests or three rectangular parallelepiped model piles in the visualizing observation. Pile spacings of 200 mm and 100 mm between pile centers were used in the models. Tact...

One of the main problems associated with generation wind energy in offshore platforms is analysis behavior soil when pile driven into seabed. Nowadays, due to large dimensions foundations (hollow steel piles up 8 m diameter and 15–20 cm thickness), there are no scale studies carried out that analyze mechanical deformational where as well material supports motor. This paper presents results obta...

The objective of this work is to map, in a limited area inside and outside of the worksite, the environmental impact generated by sound pollution coming from the driving of foundation piles for high rise buildings, as well as to observe and check if the noise levels produced by the emitting source are tolerable in the urban environment. The methodology of the work includes a survey of technical...

The numerical study has been conducted to investigate the behaviour of spun pile – cap connection based on common practice in Indonesia. piles manufactured Indonesia have low confinement where amount transverse reinforcement is less than 20% minimum requirement set by ACI 318-19. research objectives are parameters that affect connection. Three investigated are: details, effect concrete infill a...

We describe a series of experiments involving the creation of cylindrical packings of star-shaped particles, and an exploration of the stability of these packings. The stars cover a broad range of arm sizes and frictional properties. We carried out three different kinds of experiments, all of which involve columns that are prepared by raining star particles one-by-one into hollow cylinders. As ...

In order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. In the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...

One of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. Using piles is one of the ways for confronting local scour and erosion. In this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. And the effectof using piles and number of them observed on the amount of scour in three different Frude numbers. The shape ...
