摘要
Abstract
Bridge construction involves the site selection with the pier column tower over water disturbing the o-riginal flow pattern, which may cause such problems as river channel erosion, sedimentation and decline in flood drainage. When the construction of the bridge is close to the wading installations, the effect of variations of flow pattern on installations requires thorough assessment. Taking the bridge site planning of the upstream aqueduct gate of a city as the study background, this paper established a two-dimensional flow numerical model of river channel, sluice, pier and other facilities. Through the simulation of water flow under typical conditions before and after the engineering, the changes of water level, velocity and flow direction near the bridge and check gate were obtained. Combining the safe operation factor of the check gate, it provides some suggestions for bridge site selection.关键词
