【摘要】 爆破振动是爆破的主要危害之一,在爆破地震波的作用下,建筑物结构内部可能会产生连续拉扭及超载作用,从而可能造成房屋墙面抹灰脱落、结构体裂缝开裂或延伸等现象。为保证工程爆破时爆区周围建筑物的安全,有必要对爆破的振动效应进行实测和控制。本文根据工程实例现场爆破振动测试得到的数据,经数学回归分析处理,得到了适宜该爆破工程的爆破参数,并给出了在保证周围建筑物安全的前提下石方爆破药量。更多还原

【Abstract】 Blasting vibration is one of the major hazards of blasting engineering.Under the action of the blasting seismic waves,the internal structure of the building may produce the continuous tension-torsion and overloading effect,which may result in housing wall plaster detached and structure cracking and so on. For the safety guarantee of building in near field blasting zone,tests and controlling measures on blasting vibration effects are necessary.This thesis based on the test data obtained from the on-site blasting vibration,and gained the appropriate blasting parameters by mathematical regression analysis and processing,and the safety amount of blasting explosives under the premise of safety guarantee of adjacent buildings was given out.更多还原
