description The invention provides a comprehensive geological exploration method for an interface between a large-porosity giant loose body talus and bedrock. The comprehensive geological exploration method is characterized in that: advance geological forecast is combined with geological drilling, the advance geological forecast is adopted for performing comprehensive geological forecast on geological conditions of a talus in front of a tunnel, then geological conditions of surrounding rocks in front of the tunnel are prejudged according to the data acquired by means of the advance geological forecast, the prejudgment is divided into three segments according to mileage segments, namely, an exact talus segment, an intermediate fuzzy segment and a determined bedrock segment, necessary geological additional exploration drillings are only distributed in the intermediate fuzzy segment according to exploration requirements, and finally an exact joint mileage and position of the talus and the bedrock areconfirmed through refine
