The invention discloses a faced rock-fill dam rolling density and humidity rapid detection method. According to the invention, a faced rock-fill dam detection point position is determined; detection point coordinate is recorded; a detection hole is drilled right at the detection point, until a detection layer depth is reached; and a nucleon density gauge probe is placed into the detection hole, such that rolling density and humidity are detected. According to the invention, from respects such as auxiliary tool design, field detection method, and detection processes, problems such as accurate drilling and detection depth are solved, such that a nucleon density / humidity detection method can be used in detection of faced rock-fill dam rolling density and humidity. A detection depth can reach 100cm. The method can also be used for detecting parameters such as dry density, compaction degree, and the like, such that high-intensity construction quality detection requirement of dam construction can be satisfied. According to the invention, an indirect geophysical detection technology is adopted. Only 1 or 2 small holes with depths reaching the rolling thickness are needed to be drilled on a detection surface, and density and humidity detections can be rapidly completed without digging. The method provided by the invention belongs to a non-destructive detection technology.
