Embodiment Construction
[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings, in which several embodiments of the present invention are shown, but the present invention can be realized in different forms, and is not limited to the text described On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.
[0032] Such as figure 1 As shown, an on-site calibration method for in-situ testing test equipment includes the following steps:
[0033] S1. Indoor calibration and correction of in-situ test equipment:
[0034] S1-1. Use the sensor calibration device suitable for in-situ test equipment to calibrate the sensor of the test equipment: place the in-situ test equipment on the sensor calibration device, and apply real-time reading to the in-situ test equipment through the calibration device. The load value a is taken;...

The invention provides a method for on-site calibration of in-situ test equipment, including 1. indoor calibration and correction of in-situ test equipment, and the in-situ test equipment that meets the indoor calibration requirements is the equipment to be tested; 2. the equipment to be tested On-site calibration and correction: find a standard test site suitable for on-site calibration, perform on-site calibration of the equipment to be tested in the standard test site, judge whether the equipment to be tested meets the requirements of on-site application, and judge whether the equipment to be tested that does not meet the requirements of on-site application meets the requirements of the site Calibration requirements and accuracy testing of equipment. The calibration method provided by the present invention can reduce the gap between the force mode and the force mode in the soil during the actual operation, thereby improving the test accuracy of the in-situ test test equipment calibration, and avoiding the design and construction difficulties of subsequent projects. Increased project cost, reduced safety of engineering construction and other issues; have the corresponding calibration equipment, and provide a standard test site for the experimental research of the actual application of the equipment, which brings new opportunities for the research and development of new in-situ test technology and test equipment. It is convenient, and at the same time saves the research and development cost of in-situ testing technology and test equipment, and accelerates the research and development speed.
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...
