- Abstract
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.
