1 引言 为了研究避免高潮汐水流对威尼斯域的影响,Padua大学的普利林(G. Poleni)水力学研究所对此进行了一系列的试验研究。这些研究包括再现威尼斯湾的一个整体模型试验和它的三个入口局部模型试验。整体模型模拟范围约12000m~2,如图1所示。模型按沸汝德相似准则设计,其垂线比尺为1:20,平面比尺为1:250,模型变态率达12.5。另外三个入口局部模型也按佛汝德相似准则设计,模型比尺为1:60。这三个入口的名称分别为丽多(Lido),马来莫口(Malamoao)和谢家(Chiogga)。本文着重探讨了以上这些模型试验中所遇到的一些问题,其重点放在马来莫口入口模型上。
1 INTRODUCTION In order to study the effect of avoiding high tidal currents on the Venice area, a series of experimental studies have been carried out by the G. Poleni Institute of Hydraulics at Padua University. These studies include a holistic model test to reproduce the Bay of Venice and its three-entry partial model test. The overall model simulation range of about 12000m ~ 2, shown in Figure 1. The model is designed according to the similar criterion of boiling Rude. The vertical scale is 1:20, the plane scale is 1: 250 and the metamorphosis rate is 12.5. The other three entrance partial models are also designed according to the Froude similarity criterion with a scale of 1:60. The three entrances are named Lido, Malamoao and Chiogga respectively. This article focuses on some of the problems encountered in the above model tests, focusing on the Malayokoukou model.
