摘要
获得国家科学技术进步一等奖的“1485抗爆激波管”是用来模拟爆炸冲击波的室内试验设备，其驱动段是以燃烧火药为能源，锥管前面管体内径是348mm，锥管后面试验段及其出口段内径为1485mm。试验段内部超压可达0.05～1.20MPa。地上试验段参试物安装在管内。地下试验段是内径2.50m、高3.00m的箱体，内部可进行地下结构模型试验。驱动段膜片夹紧力是由8个油缸及其二级连杆增力机构来完成。有长江三峡大坝动力响应试验、地下隧道试验、地形对冲击波影响试验及人防工事试验等已做过的部分典型试验。
This paper presents “ Φ 1485 blast resistance shock wave tube”, which won the first prize for Science and Te chnology Progress from the State. This tube is a house test facility used to simulate the shock wave in the air. Gunpow der is used as the energy source in the driving section. The inside diameter at the front of the conical tube is 348mm. That of the test section and exit sectio n at the rear of the conical tube is 1485mm. Inside overpressure of the test s e ction can reach 0.05～1.20MPa. The specimen is installed inside the aboveground test section. Underground section inside which underground structure model tests can be performed is a box which is 3m high with an inside diameter of 2.50m. Th ere are 8 oil cylinders providing clamp force for the metal plate in the driving section. This paper mainly presents part of the completed typical t ests including dynamic response test of Three gorges dam; underground tunnel te st; the affect of terrain on shock wave test; civil defense works test, etc.
