Abstract

The invention belongs to the technical field of geotechnical investigation and detection and discloses a soil bonding curing agent and a soil detection method. The soil bonding curing agent comprises the following components in parts by weight, 40-70 parts of fly ash, 15-40 parts of asphalt and 10-30 parts of silicone oil. The detection method comprises the following steps of acquiring data of test indexes of an actual soil sample and a bonded cured soil sample, establishing a working curve, bonding and fixing a to-be-detected soil sample and a soil bonding curing agent, and sending to a laboratory for detection to obtain detection parameter indexes; and finally, calculating according to a fitting formula of the working curve to obtain actual parameter indexes of the soil sample to be detected. According to the detection method disclosed by the invention, special protection measures do not need to be taken on the taken cohesionless sedimentary soil or high-saturation soft soil sample, and the subsequent soil sample to be detected can be conveniently subjected to indoor test detection through pre-data acquisition and working curve establishment; and detection convenience and accuracy are greatly enhanced.
