摘要

摘要设计不良的涵洞入口结构会引起冲蚀,导致涵洞倒塌,对周边土地造成重大破坏。对一组室内试验进行了评估,以检查涵洞入口的速度分布。采用三维多普勒测速仪测量了涵洞上游的瞬时流速。分析了平均流速、湍流强度和雷诺数应力,以了解涵洞入口附近的流动结构。

Velocity Field Characteristics at the Inlet to a Pipe Culvert
Abstract A poorly designed culvert inlet structure causes scouring, which can lead to the collapse of the culvert and significant damage to the neighboring land. A set of laboratory tests was evaluated to examine velocity distribution at the culvert inlet. A three-dimensional acoustic Doppler velocimeter was used to measure instantaneous flow velocity upstream of the culvert. The analysis of mean velocities, turbulence strength, and Reynolds stresses was performed to understand the flow structure near the culvert entrance.
