A Review of Application and Research Progress of Seismic Isolation Technology in Isolation Trench. (English)

As a new form of environmental pollution, artificial vibration is listed as one of the world's seven major environmental hazards. Various forms of artificial vibration involve the generation and propagation of elastic waves. Setting up isolation trench between existing vibration sources and protected areas to cut off the propagation path of elastic waves, attenuating vibration energy and reducing vibration amplitude is a common vibration isolation measure used in rail transit, explosion, pile driving, impact and other common engineering situations. In addition, the vibration energy generated by ground motion is much higher than that of artificial vibration, and the propagation range and distance are more far-reaching. Therefore, the experimental research, theoretical research and finite element simulation research on the principle and effect of seismic isolation trench under the action of ground motion and artificial vibration are very important. In order to provide theoretical support for practical engineering, we have made a detailed arrangement of the seismic isolation technology at home and abroad in the past 30 years.

人工振动作为一种新形式的环境污染, 被列为世界七大环境公害之一。各种形式的人工振动都涉及弹性波的产生和传播, 在振源与保护区之间设立隔振 (震) 设施来切断弹性波的传播路径, 衰减振动能量, 降低振动幅度是目前在轨道交通、爆炸、打桩及撞击等常见的工程情况下普遍采用的隔振 (震) 措施。此外, 地震动所产生的振动能量远远高于人工振动, 传播的范围和距离更加深远, 因此在地震动及人工振动作用下隔振 (震) 沟的减隔振 (震) 原理及效果的试验研究、理论研究及数值分析研究具有非常重要的意义。本文对近30年来国内外减隔振 (震) 技术进行了较为详细的整理, 以期为实际工程提供理论支撑。 [ABSTRACT FROM AUTHOR]
