桥梁防撞设施物理模型试验

Experiment on Physical Model of Bridge Anti-collision Facilities

物理模型试验是预报防撞设施所受撞击力及优化设计方案的主要方法之一。结合杭州湾大桥柔性防撞设施及东海大桥独立式防撞体设计方案,阐述了船—防撞体撞击试验的基本原理、方法、试验方案及相关试验结果。提出了柔性防撞系统的优化方案。试验结果表明,该方案经济有效,可供预报类似桥梁防撞设施撞击力时参考。

Model test is one of main methods for predicting exerted impact force and optimizing design scheme of anti-collision facilities. Based on the projects of flexible anti-collision system for the Hangzhouwan bridge and the design of collision-proof devices for the Donghai bridge, the basic principle and testing method of collision between vessel and anti-collision facility, the test schemes and related test results are briefly introduced. An optimized scheme of flexible anti-collision system is proposed by model test. The tests show that the scheme is effective and economical. The research can be help to impact prediction of similar bridge＇ s anti-collision facilities.
