【摘要】 传统钻探方法进行人工挖孔灌注桩基础检验往往费工、费时、检验成本高,且探查深度有限。为此考虑采用地震映像法作为主要检测手段,少量的钻探作为对物探分析结果的验核,以提高检测速度、节省检测费用。介绍了地震映像法的基本概念和应用原理,探讨了其应用于桩基础检测的有效性。通过工程实例探讨该方法在实际应用应采用的检测方式和数据分析方法,针对检测结果对该方法的有效性进行了分析,并总结了操作过程中应注意的事项。结果表明地震映像法进行桩底岩层检测是可行有效的。更多还原

【Abstract】 In order to increase the testing speed and save the testing cost in the test of manual hole-digging pile foundation,this paper adopts seismic imaging method as the main testing means and partly uses drilling method as testing the geophysical analyzing result.In this paper it firstly introduces the basic concept of the seismic imaging method and its application principle.Then it explores the effectiveness of the method that is applied in the pile foundation testing.Based on the testing result,it analyzes the effectiveness of the method and finally summarizes the points for attention in the process of operation.更多还原
