目前国内用于模拟地震的振动平台按用途划分大体可以分为两种,一种是用于科研(实验),另一种是用于体验(科普)。这两种振动平台由于用途不同,所以技术要求和技术指标以及工艺处理就有很大差别。随着从国家层面到社会大众对防震减灾科普宣传的重视度的提高,防震减灾部门在做好业务工作的同时,也急需加大在科普宣传方面的工作投入,那么能够将试验和体验结合在一起的模拟地震平台在地震行业会有广阔的应用前景。本文结合山东省地震应急救援训练基地对模拟地震实验(体验)平台的建设需求,对该项研究的背景、建设方案和理论技术等进行了介绍,并重点对模拟地震实验(体验)平台的基本原理和关键技术进行了分析研究,并就建设该项目的几个关键问题,如负载、加速度、最大位移、最大速度等进行详细讲解。结合本行业的实际需求和今后业务的发展规划,为同行业建设类似项目提供了可靠的技术参数、可行的技术方案和宝贵的建设经验,在本行业也能起到一定的示范作用。
At present, the vibration platform used to simulate earthquakes in China can be roughly divided into two types according to purposes, one for scientific research (experiment) and the other for experience (popular science). The two vibration platform due to different purposes, so the technical requirements and technical indicators and process are very different. With the improvement of publicity on science and technology for earthquake disaster prevention and reduction from the national level to the general public, earthquake prevention and disaster reduction departments, while doing a good job in business, are also in urgent need of stepping up their investment in science popularization and publicity so that they can integrate experimentation and experience in Simulated seismic platform together in the earthquake industry will have broad application prospects. In this paper, the background, construction scheme and theory and technology of this research are introduced according to the construction requirements of the experiment platform for earthquake simulation and rescue in Shandong Province, and the emphasis is put on the basic of the experimental platform Principle and key technologies were analyzed and studied, and several key issues of the construction of the project, such as load, acceleration, maximum displacement, maximum speed and so on to explain in detail. Combined with the actual needs of the industry and future business development planning for the industry to provide similar projects with reliable technical parameters, feasible technical solutions and valuable experience in the construction industry can play a role model.
