摘　　要：地震勘探作业中众多保护物的安全控制标准并无规范可依,因此通过多种方法的分析和相互验证确定合理的振动安全控制标准尤为重要。以山东省胜利油田东部探区为例,首先基于应力波和破坏准则的理论对各类保护物的强度进行验算,然后考虑爆破振动对人居环境的影响和各类保护对象抗震设防要求,并采用现有规范进行校验,最后选取4种方法中的最小值作为胜利油田东部探区不同保护对象的地震勘探振动安全控制标准。研究结果表明:强度验算确定的控制标准值一般比抗震设防和规范控制标准宽松得多,抗震设防和规范要求具有较大的安全富余,瑞利波传播速度理论上为横波传播速度的0.87~0.95倍;对于地表建筑物,应采用面波进行受力分析,对传播介质内部建筑物应采用体波进行强度验算。Standards for safety control of many protective objects in seismic exploration operations have no guides.Therefore,it is important to determine a reasonable vibration safety control standard through analysis and mutual verification of various methods.Firstly,based on the theory of stress wave and damage criterion,the strength of various protective objects in east exploration area of Shengli Oilfield was checked.Then the impact of blasting vibration on the human settlement sites and the seismic protection requirements of various protected objects were analyzed,and the existing specifications were used to verify the previous checking results.Finally,the minimum values calculated by four different checking methods were used as the seismic safety control standard for protection objects.The research results show that the control standard values determined by the strength check calculation are generally less strict than the anti-seismic codes,and the requirements in anti-seismic codes have greater safety margins.The Rayleigh wave propagation velocity is theoretically 0.87 to 0.95 times of the shear wave propagation velocity.For the surface buildings,surface waves should be used for stress analysis,and for buildings inside the propagation medium,body waves should be used for strength checking.
