某工程爆破及机车振动作用下房屋响应的研究
|
摘要
工程爆破及震动对地表建筑物会造成一定程度的损伤.以临合高速公路为背景,对该工程隧道爆破及机车震动的强震动实时测试和分析,并对附近房屋的损伤程度进行了宏观调查,分析得出地表震动特性、震动影响范围和程度,及其对房屋结构的影响.为类似工程爆破及震动的设计及施工安全管理提供参考和依据.
Blasting and vibration will cause a certain degree of damage to the buildings on the surface of the earth. In this paper,taking the highway as the background,the real-time test and analysis for engineering tunnel blasting and strong locomotive vibration was conducted,and macroscopic investigation of the degree of the nearby house damage was made. The characteristic of the surface vibration,the scope and degree of the vibration influence,and the impact on building structure are got from the analysis,and some references are provided for the design and construction of the similar engineering blasting and vibration.
