Purpose: The aim of this work is the construction bridge structures on a soil foundation with physical and mechanical characteristics, often differing from survey activity parameters. Technical regulations supports envisage plate-bearing test drilled pile foot. Design/methodology/approach: quality improvement not only preparation, but also requirements for structural reliability, approximated R...

Pile foundation bridges are structures extending in the middle of sea, so they subject to currents, waves, and earthquake forces. This article presents a hybrid simulation that was used with input excitations different current velocities, wave properties, amplitudes assess non-linear dynamic behavior pile bridge piers. Based on interface between MATLAB ABAQUS software, general formulations flui...

What’s a question to your answer? We will not settle this puzzle here, yet we’ll taste it. But let’s begin at the beginning, namely in 1907, when Willem Abraham Wythoff [7], a Dutch mathematician, invented the game we analyze here, explained vividly by Martin Gardner in [5]. The game is played with two piles of tokens, each pile containing an arbitrary number of tokens. A move consists of eithe...

An open ended pipe pile can become plugged when sufficient frictional resistance is developed by the inner soil cylinder within the pile (soil plug), thereby preventing further intrusion of the soil into the pile. When plugging occurs in an impact driven pipe pile, a complex interaction between the pile and soil plug takes place, causing the propagating stress wave to undergo an abrupt change. ...

The tie cable of the half-through tied-arch bridge generally uses external prestressed cables, which need to be replaced regularly similarly cables and suspenders, but there is very little research in this area at present. Aiming a method replace for kind bridge, study takes third Lingjiang had damage cable, as an example. Based on whether temporary force-replacement structure, eight replacemen...
