一、地基震动特性调查及常时微动测定的意义迄今为止,预报地震的发生还有一定的困难,强烈地震往往给人类带来灾害性的灾难。但是,可以设法最大限度地减轻地震灾害,特别是减轻对建筑物的震害。建筑物的破坏程度受地震的震级、传播路径、地基及建筑物自生的振动特性等因素的影 First, the foundation vibration characteristics investigation and the significance of the constant micro-motion measurement so far, there are certain difficulties in forecasting the occurrence of earthquakes, strong earthquakes often cause disasters to human disasters. However, we can try to minimize the earthquake disaster, especially to reduce the damage to buildings. The degree of damage to a building is affected by factors such as the magnitude of the earthquake, the propagation path, and the vibration characteristics of the foundation and the building itself.
