The invention provides a field calibration method for in-situ test equipment. The method includes the steps of: 1, performing indoor calibration and correction on the in-situ test equipment, and taking the in-situ test equipment meeting an indoor calibration requirement as to-be-detected equipment; and 2, on-site calibration and correction of the to-be-detected equipment: searching a standard test field suitable for on-site calibration, carrying out on-site calibration on the to-be-detected equipment in the standard test field, judging whether the to-be-detected equipment meets the on-site application requirement or not, judging whether the to-be-detected equipment which does not meet the on-site application requirement meets the on-site calibration requirement or not, and carrying out precision detection on the to-be-detected equipment. According to the provided field calibration method for the in-situ test equipment, the difference between a stress mode and a stress mode in a soil body in an actual operation process can be reduced, so that the calibration test precision of the in-situ test equipment is improved, and the problems of difficulty in design and construction of subsequent engineering, increase of engineering cost, reduction of engineering construction safety and the like are solved; and the in-situ test equipment is provided with corresponding calibration equipment, and provides the standard test field for experimental research of practical application of equipment, so that convenience is brought to research and development of a new in-situ test technology and test equipment, meanwhile, the research and development cost of the in-situ test technology and test equipment is saved, and the research and development speed is increased.
Description
technical field [0001] The invention belongs to the field of geotechnical engineering, in particular to an on-site calibration method for in-situ test equipment. Background technique [0002] With the continuous development of geotechnical engineering, the in-situ testing technology represented by static penetration testing has the advantages of rapid testing, no need to take samples, continuous operation, large amount of test data, small disturbance to soil, and more accurate data. It has been vigorously developed due to the advantages of being close to the original parameters of the soil. With the continuous deepening of the research on modern multifunctional in-situ testing technology, the corresponding in-situ testing technology theory and test equipment tend to be diversified. However, there is currently a lack of a more standardized test site for the new in-situ test technology theory and new test equipment to test its actual application effect. Taking the pore press...
