it is proposed to use a single base platform in the persian gulf considering its low depth and more appropriate environmental conditions in comparison to north sea and mexico gulf where this kind of platform is very popular. the pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. using sacs 5.3 sof...

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...

Introduction. In several earlier papers [5] and [6], we discussed single pile games of Nim in which the number of counters that can be removed varies during the play of the game. In [4] we showed how to effectively play the single-pile game in which the number of counters that can be removed is a function of the number removed on the previous move. In that paper we constructed a number base and...

Pile-up and dead-time are two main causes of nonlinearity in the response of a PET scanner as a function of activity in the field of view (FOV). For a given scanner and acquisition system, pile-up effects depend on the material and size of the object being imaged and on the distribution of activity inside and outside the FOV, because these factors change the singles-to-coincidences ratio (SCR)....

Considering viscoelastic saturated soil, The transient dynamic response of an elastic pile is studied. The pile-soil system is divided into thin layers, the control equations of the soil are solved respectively by using Laplace transform. Considering the mixed boundary-value conditions at the interface of pile and soil, expression is derived to describe the relationship between the inner force ...

Determination of negative skin friction force and The neutral plan is one the challenges which face geotechnical engineers. Unfortunately, decreases bearing capacity pile because extra compressive on pile. In this research, a 3D FE models were used to investigate behavior single group in soft soil for surcharge load as embankment fill. And what are differences that will happen group. For fill l...

Abstract The compaction effect of extra-long prestressed high-strength concrete (PHC) piles in deep soft soil foundation was studied by field test. pore water pressure gauge, inclinometer were embedded different plane positions or depths the to monitor and deformation when driving pile. research shows that magnitude excess caused single pile installation is mainly related buried depth measuring...
