古建筑的爆破安全允许振动限值研究
|
摘要
古建筑由于建筑结构和材料与现代建筑不同,而且历时漫长可能遭受到自然和人为的破坏,因此在保护此类建筑不受爆破振动破坏时,其安全允许振动限值应经论证选取。本文结合一起为保护国家级文物(六胜塔)进行的爆破振动监测,通过脉动测试和试爆测试,分析古塔结构反应,确定古塔的安全允许振速,更科学地控制爆破施工对古建筑的振动影响。
The ancient buildings' structures and materials are different from modern ones,and may suffer the natural and man-made damage of a long period of time. Therefore,the allowable safety vibration limit of such constructions should be determined by the demonstration so as the buildings to be free of blasting vibration damage. This article,based on blasting vibration monitoring by taking an example of the protecting national cultural relic (Liusheng Tower),analyzed the ancient tower's structure responses to vibration through pulsating test and experimental blasting,and determined the allowable safety vibration velocity of the ancient tower,which are responsible for the more scientifically control of the blasting vibration impacts on the ancient buildings.
