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...

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 ...

Soldier Station is a unique simulation system which bridges the gap between two distinct realms of modeling: constructive and virtual. The Soldier Station operator controls a simulated dismounted infantry soldier in a 3D virtual environment with rules of movement, engagement and tactics provided from a constructive model. This paper describes the Soldier Station system, its design, and the inte...

The use of audio sensors for soldier systems is examined in detail. We propose two applications, speech recognition and speaker veri cation. These technologies provide two functions for a soldier system. First, the soldier has hands-free operation of his system via voice command and control. Second, identity can be veri ed for the soldier to maintain the security integrity of the soldier system...

In the recent years, non-connected piled raft foundation has been considered as an economical and practical deep foundation in the situation that high shear and concentrated loads may occur at the connection of the raft and pile head. This paper was presented an experimental study of a square foundation on the effects of parameters such as S/D, L/D and etc. in two cases of connected or non-conn...

a simplified approach for nonlinear analysis of the load-displacement response of a single pile and a pile group is presented using the load-transfer approach. a hyperbolic model is used to capture the relationship between unit skin friction and pile-soil relative displacement developed at the pile-soil interface and the load-displacement relationship developed at the pile end. as to the nonlin...

Original scientific paper In this paper, based on the overlapping deformation mode of load transfer law of uplift belled pile, and the theory of elastic mechanics, the elastic-plastic analytical solutions of uplift belled pile were derived, and the nonlinear elastic-plastic deformation analysis method was established, which made the deformation analysis theory of uplift belled pile more reasona...
