This paper presents the use of genetic programming (GP) as a tool to predict pier scour depths based on clear-water conditions of laboratory measurements by past researchers. Four main dimensionless parameterspier width, approaching flow depth, threshold flow velocity, and channel open-ratio are considered for predicting the scour depth. The performance of the GP equation is verified by compa...

In order to understand the load sharing and settlement reduction behaviour of piled raft resting on soft clay, 1g model tests were conducted on small-scale models. The parameters studied were the effect of pile length and number of piles. The load settlement behaviour obtained from the tests has been validated using simplified method (Polous & Davis). Equivalent pier concept of Poulos and Davis...

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...

I, Bomo Edith Edna Molewa, Minister of Water and Environmental Affairs, hereby publish the White Paper on the National Environmental Management of the Ocean, as set out in the schedule hereto. The White Paper will also be available on the Department's website at www,environment.gov.za. Copies of the English version of the White Paper are available at the offices of the Department's Oceans and C...

Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic response. As such, this paper proposes a new approach for balancing the ductility demand in irregular bridges by utilizing shape memory alloys (SM...
