摘　　要：依据《工程场地地震安全性评价GB17741-2005》、《岩土工程勘察规范GB50021-2001》等现行国家规范,对地震工程地质条件勘测中钻探相关工作的基本要求和存在的问题进行了探讨,并提出了具体措施和建议。给出了土样深度、土层分层深度、标准贯入试验点深度等钻孔相关深度数据的测量方法。归纳了地震工程地质单元层的划分原则,并介绍了应用该原则编制钻孔柱状图的步骤。Based on ＂Evaluation of Seismic Safety for Engineering of Geotechnical Engineering GB50021 - 2001＂ and other current Sites GB17741 -2005＂,＂ Code for Investigation national standards, the basic requirements and problems of drilling and related work on investigation of seismic engineering geological conditions were discussed, and some concrete measures and suggestions were proposed. The measurement method for drilling-related depth data such as soil sample depth, soil layered depth, the depth of standard penetration test point was given. The division principles of seismic engineering geological unit layer were summarized. Using the principles, the steps to draw up drilling histogram were introduced.
