井塔是矿井的咽喉建筑,顶层安设多绳提升机,把井下开采出来的矿石提升上来,负担着井上下的垂直运输。井塔的水平地震荷载计算和动力分析模式的建立都基于振动性状的实测资料。然而,由于原型振动试验比较少,这方面资料很少,急待于开展并积累,根据《工业构筑物抗震规范》编制工作的需要,笔者对广东省仁化县境内的凡口铅锌矿的主副井塔进行了强迫振动试验和自然脉 The well tower is a throat building of a mine. A multi-rope hoist is installed on the top of the well and the ore extracted from the mine is lifted up to take up and down the vertical transportation of the well. The horizontal seismic load calculation and dynamic analysis model of the well tower are based on the measured data of the vibration properties. However, due to the relatively small number of prototype vibration tests, there is little information in this area, and it is urgent to carry out and accumulate. According to the requirements for the preparation of work on the “seismic codes for industrial structures”, the author of the present study is to the masters of the Fankou lead-zinc mine in Renhua County, Guangdong Province.
