悬索桥健康监测实验教学平台开发与应用
Research and Exploration in Laboratory（2021）
Abstract
为丰富桥梁实验与检测课程的教学资源,设计了悬索桥健康监测实验教学平台.平台包括模型桥和健康监测系统等组成部分.以大连市北大桥为例,设计和制作了总长12.14 m、主梁宽1.1 m、塔高1.95 m的三跨悬索桥模型.在此模型桥上建立了完整的结构健康监测系统,通过布设各类传感器对桥塔倾斜、主梁应变、主梁挠度、桥体振动、伸缩缝变形以及环境温湿度进行在线监测,实现了自动化采集、无线传输、远程查看、实时预警等功能.利用该模型可在实验室内演示桥梁结构健康监测全过程,开展不同层次的实践教学内容,有助于学生对桥梁健康监测原理和方法的理解,对实践教学具有积极的促进作用.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
