In previous researches, to avert the aggravation of pile penetration during embankment filling, end-bearing piles such as CFG piles were not recommended to reinforce the soils with low shear strength.
These being required due to the very shallow underlying bedrock, which only allows for a limited sheet pile penetration. Access is provided by a temporary access works platform (pictured) allowing safe working over water.
Feng and Deschamps [27] used the finite difference program, FLAC, to simulate the pile-hammer-soil system in which several variables including soil strength, pile-soil interface friction angle, lateral earth pressure coefficient, hammer operating frequency, bias weight, hammer centrifugal force, and pile embedment were examined to assess their relative importance in pile penetration rate.
Stopwatches with the precision of 0.01 s are used to record penetration time, and the time per half one meter of pile penetration is recorded; besides, a camera is fixed to record the pile sinking process for checking in later.
Their study focused on small scale laboratory tests where the horizontal and vertical chamber pressure, the number of hammer blows, pile penetration depth ratio, and mean normal stress of the soil were set as inputs of the network model while the ultimate bearing capacity was selected as the model output.
Describing one of the LHD's key features, Ben Thompson, product manager at Atlas Copco, said "[An] optimized bucket means better muck pile penetration, faster acceleration and faster dumping.
A new bucket and a unique boom design, combined with variable displacement pumps, plus the Atlas Copco Rig Control System, which monitors and controls all aspects of the operation, results in superior muck pile penetration, less wear and tear on the machine, and an overall faster and more productive loading cycle, according to the company.
The pile penetration depth under the maximum tensile force was also computed by the Japanese bridge construction standard (2002), API recommended practice 2A-WSD, AASHTO, and Broms' analysis method.
--layer 1, thickness 10.0 m, pile penetration in this layer is 5.0 m (to bottom of pile);
