The assessment of pile drivability is the premise successful installation, and completely weathered (CW) rock may bring risk refusal. This paper presents a case driving refusal that occurred in CW gneiss layer. physical mechanical properties are analyzed based on results laboratory test, cone penetration test (CPT), standard (SPT). By comparing with those from intact gneiss, layer this study wa...

In this paper, numerical analysis of a pile-soil interaction problem is presented considering the parameters influencing the axial load-deformation behavior of the pile embedded in a layered soil medium. The analysis is demonstrated with parametric solutions of a pile with underlain model soil strata under the axial force. An attempt is made to ascertain the extent of influence of elastic prope...

Using a series of model tests, this study investigated the effect of a passive pile on 3D ground deformation around a laterally loaded pile and on that laterally loaded pile's response in sand. The active pile head was subjected to lateral loads, and the passive pile was arranged in front of the active pile. In the model tests, the distance between the two pile centers was set to zero (i.e., a ...

As part of global efforts to reduce dependence on carbon-based energy sources there has been a rapid increase in the installation of renewable energy devices. The installation and operation of these devices can result in conflicts with wildlife. In the marine environment, mammals may avoid wind farms that are under construction or operating. Such avoidance may lead to more time spent travelling...

Prediction of pile bearing capacity has been considered an unsolved problem for years. This study presents a practical solution the preparation and maximization capacity, considering effects time after end driving. The prediction phase proposes intelligent equation using genetic programming (GP) model. Thus, geometry, soil properties, initial driving were predictors to predict capacity. develop...

Compared with conventional piles such as the circle pile, the cast-in-place large-diameter pile (PCC pile) has many advantages: the lateral area of PCC pile is larger and the bearing capacity of PCC pile is higher. It is more cost-effective than other piles such as square pile under the same condition. The deformation of the PCC pile is very important for its application. In order to obtain the...

alcohol production from molasses can lead to large amounts of wastewater that cause serious environmental concern. it is characterized with extremely high organic loading rate, high turbidity and dark brown color .composting this kind of wastewater is a biothermal aerobic process that during composting heat generated by the composition of the organic material reduces the moisture content of the...

In the field of PHC pile joints, it is important that prestressed high-strength concrete pipe piles are referred to as piles. conventional hoops, bamboo-like joints protrude from joint position at surface pile. Driving in, disturbing soil around pile, and affecting frictional resistance serious issues. To address such issues, herein, a new type clamping proposed. A method presented determine si...
