Geotechnical engineering geological investigation system and investigation method thereof

The invention discloses a geotechnical engineering geological investigation system and an investigation method thereof, and belongs to the technical field of geological investigation. The method and the device are used for solving the technical problems of poor local normative monitoring analysis effect and poor overall reliability expansion management effect of geological survey implementation in the existing scheme. The method comprises the following steps: carrying out monitoring and data statistics on investigation and detection implemented by a plurality of preset representative detection points in a monitoring area, carrying out investigation and detection implementation dimension data processing and calculation on the plurality of representative detection points according to an investigation and detection summary set obtained by statistics, and obtaining and analyzing investigation implementation evaluation coefficients corresponding to the plurality of representative detection points; integrating and
