1 Scope

GB/T 15314-2024 is the Chinese national standard on specifications for precise engineering survey, in the field of natural and applied sciences. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 28 May 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2024. Classification: ICS 07.040, CCS A78. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the precise engineering survey control network, survey mark construction, precise angle measurement, precise distance measurement, precise height measurement, Technical contents and requirements including precision alignment measurement, precision vertical measurement, precision three-dimensional measurement, as well as data processing, quality control and results management. This document is applicable to precision measurement work in various stages of survey and design, construction layout, installation and commissioning, deformation monitoring, etc. of various projects.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Use high-precision measuring instruments and special equipment, use corresponding measurement methods and data processing means to achieve absolute measurement accuracy Engineering surveying work with millimeter level or above or relative accuracy of 10-5 or above.

3.2 Accurately measure the distance and angle of the point offset in a fixed direction, and repeatedly and accurately adjust the point to make the distance and angle of the point Measurement method where the offset is less than the error requirement.

Note. It is generally used for the precise installation of precision components in space according to the designed position. The tension wire method, optical measurement method and photoelectric measurement method can be used as needed. method.
