1 Scope
This code specifies the basic technical requirements for the engineering survey, geotechnical engineering survey, and hydrological survey of large crossing overhead transmission lines.
This code is applicable to the exploration and surveying of 220 kV-750 kV large crossing overhead transmission lines. Ⅰt can be taken as a reference for exploration and surveying of large crossing overhead transmission lines at other voltage levels.
Ⅰn the case of strain sections of lines crossing wide navigable rivers, lakes or straits with large spans (generally above 1000 m) or high towers (generally higher than 100 m) for which special consideration shall be taken in conductor selection or tower design and faults of them may severely influence navigation or are extremely difficult to repair. Under these circumstances, the lines shall be surveyed as large crossing projects.

2 Normative References
The following normative documents contain provisions which, through reference in this text, constitute provisions of this code. For dated references, subsequent amendments (excluding the corrigendum) to, or revision of, any of these publications do not apply. However, parties to agreements based on this code are encouraged to investigate the possibility of applying the latest editions of the normative documents indicated below. For undated references, the latest edition of the normative documents apply.

3 General Provisions
3.0.1 This code is established to unify the technical standards for exploration and surveying of large crossing overhead transmission lines, ensure that the lines are technically advanced and cost effective and the strain sections of the lines can operate safely and normally.
3.0.2 The exploration and surveying of large crossing overhead transmission lines involve engineering survey, geotechnical engineering survey and hydrological survey, aiming at providing accurate and reliable design basis and basic data for the design, construction, and operation of large crossing lines.
3.0.3 The exploration and surveying of large crossing overhead transmission lines shall be divided into three stages consisting of feasibility study, preliminary design and construction drawing design in order to accommodate the requirements of different design stages. Ⅰf the scheme for large crossing lines is definite and the conditions are simple, these stages can be combined, provided that the design requirements of all stages are satisfied. Ⅰf there are special requirements for the projects, corresponding exploration and surveying stages can be included.
3.0.4 Ⅰn the exploration and surveying of large crossing overhead transmission lines, the new technologies and equipment shall be actively promoted.
3.0.5 Ⅰn addition to this code, the exploration and surveying of large crossing overhead transmission lines shall also comply with the current related national codes and industrial standards.
