The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

Achieving scalability is one of the goals of the database research community at present. The Internet is estimated to have a few hundreds of nodes, yet the largest database systems in the world scale up to at most a few hundred nodes. Supporting large databases is still a challenge because of the lack in the degree of distribution. The main goal is for databases to scale over Internet, thus mak...

This short note adds some results in parallel to those given in [1] on the random variable height on the set of watermelons with wall. In this paper we prove weak convergence results for the random variables “height” and “range” on the set of watermelons without wall restriction, as well as asymptotics for the moments of the random variable height. The techniques applied are quite similar to th...

Three-dimensional model is established with finite difference method to simulate construction process based on design and construction plans of existing overpass pile foundation adjacent to certain large-section railway tunnel in Chengdu, China. Ground, isolation pile, main bridge pier and ramp pile near the tunnel are taken as research object, and surface settlement amount, displacement change...

The local scour around bridge piers is one of the main causes failures. In this study, hole dimensions circular were investigated under clear water conditions for various steady flow rates. experiments performed with four different pier diameters and seven rates by using uniform sediment a median diameter 1.63 mm geometric standard deviation 1.3. After each bathymetry was determined. New empiri...
