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...

Ports are the most important economic, political and military bottlenecks. This puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. Pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. Correct and exact estimation of...

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 ...

This research is to assess the influences of inertial mass from girder on dynamic characteristic, response, and structure-soil interaction a pile-soil-pier subsystem in scale-model cable-stayed bridge. Therefore, both connection configurations between girder, including sliding fixed connections, were designed present various superstructure delivered pile-soil-pier. The supported by 3 × pile-gro...

Worldwide, urbanisation has resulted in extensive replacement of natural habitats with man-made habitats. In Sydney Harbour, Australia, approximately half of the natural foreshore has been replaced by seawalls. Many of these have wharves built over part of their length, which could affect intertidal assemblages on seawalls beneath the wharves. This was tested by sampling and comparing assemblag...
