摘　　要：介绍了《城市轨道交通岩土工程勘察规范:广东省标准DBJ/T15-241—2022》[1]的编制目的、思路原则、主要内容及创新。文献[1]结合广东省地质条件和城市轨道交通特点,在勘察工作量布置、不良地质作用与特殊性岩土勘察、水文地质条件勘察等方面作出了比现行国家和行业标准更严格或更具体的规定,以引导提升本地区轨道交通勘察质量,减少因勘察和地质原因可能造成的风险。文献[1]为首次颁布,后续使用过程中应注意保证暗挖隧道左、右线间“共用”勘探点的实施位置和完成率,进一步研究针对特殊和不良地质作用的高精度勘探与测试方法,在更大范围统一地层层序划分与编号规则,持续探索和推广应用包括勘察信息化在内的勘察新技术和新设备。Introduces the compilation purpose,thinking principle,main contents and innovation of the Code for Geotechnical Investigation of Urban Rail Transit in Guangdong Province DBJ/T 15-241—2022[1].According to the geological conditions of this province and the characteristics of urban rail transit,literature[1]makes stricter or more detailed provisions than current national standards and national industry standards in terms of planning amount of investigation required,adverse geological actions,special rocks and soils and hydrogeological conditions,so as to lead to improving the quality of geotechnical investigations and reduce the risks caused by geotechnical investigations or geological conditions.It is the first time for literature[1]promulgated.In the process of implementation,attention should be paid to ensuring the completed borehole positions and completion rate of the“shared”boreholes between the left and right lines of the underground tunnel,further studying on high-precision exploration and testing techniques for adverse and special geological actions,unifying the division and encoding rules of rock and soil layers in larger areas,and continuously seeking and popularizing the application of new equipment and technologies,including technologies for investigation information.
