3 terms and definitions

GB/T 24106 Definitions and the following terms and definitions apply to this document. 3.1 Prototype observation According to technical regulations, the engineering structure of the traits and changes in the process of dynamic monitoring and observation of technical operations. 3.2 Geotechnical prototyping instrumentation instrumentsdevotedtogeotechnicalengineeringprototypemonitoring On the geotechnical engineering structure of the characteristics and changes in the observation of the instrument collectively. Note. According to the principle of measurement is divided into angle, displacement, pressure, stress, strain and temperature measurement instruments. According to the principle of instrument structure is divided into differential resistive, vibrating wire Type, potentiometer type, photoelectric (CCD), stepper motor and capacitive instruments. Its working principle is to use the characteristics of the instrument itself to obtain geotechnical engineering Prototype observations of various parameters. 3.3 Indoor calibration Under the indoor conditions, the accuracy of the prototype observation equipment, temperature parameters and insulation resistance and other technical indicators of the calibration. 3.4 Field verification in-siteverification Prototype observation equipment installation/embedded in the engineering entity state, the stability of the instrument measurement, insulation resistance, four-core differential resistance instrument Positive and negative resistance ratio, than the measurement limit and reset accuracy and other technical indicators of the calibration.

4 General

4.1 Prototype observation equipment and connecting cables should be identified, the name of the instrument, model, the main technical parameters, manufacturer name, factory number and date, etc. ...
