Chapter 1 General Provisions
Article 1.0.1 This standard is based on reliability theory and uniformly stipulates the basic principles and methods of port engineering structure design. It serves as a common criterion for compiling and revising various volumes of port engineering structure design specifications and related survey, construction specifications and management and use regulations, so that port engineering structures meet the requirements of advanced technology, economic rationality, safety, reliability, durability and applicability.
Article 1.0.2 This standard applies to port hydraulic structures such as docks, breakwaters, and revetments of various structural types. Navigation structures such as locks and ship lifts, as well as ship repair and shipbuilding structures such as docks and slipways, can be used as a reference. This standard applies to the overall structure and the components and foundations that make up the structure, and to the use stage of the structure, as well as the construction stages such as manufacturing, transportation, installation, excavation and backfilling.
Article 1.0.3 Port engineering structures must meet the following functional requirements: 1. Able to safely withstand various actions that may occur during use and construction; 2. Have appropriate working performance under normal use and maintenance; 3. Have sufficient durability under normal use and maintenance; 4. In the event of an accident, the structure can still maintain the necessary overall stability.
Article 1.0.4 The probability that a structure has a predetermined function within a specified time and under specified conditions is called structural reliability. Article 1.0.5 The design of port engineering structures adopts the probabilistic limit state design method expressed by partial factors. For some projects, the probabilistic limit state method can be directly used for design when conditions permit.
Article 1.0.6 The time parameter based on the design of port engineering structures is the design duration, and the design duration of the permanent condition is called the design reference period. The design duration of the transient condition is called the transient duration.
Based on the structural characteristics and environmental conditions, the design reference period of reinforced concrete structures of port engineering can be set at 50 years.
Article 1.0.7 Port engineering structures should be classified into safety levels according to Table 1.0.7 based on the severity of the possible consequences after damage (endangering human life, causing economic losses, and generating social impacts, etc.). Structures with different safety levels should be specified with corresponding reliability.

Consequences of damage
Very serious
Note: The safety level of general port engineering structures should be taken as Level 2. Level 3
Not serious
Article 1.0.8 Port engineering structures and their components should take the same safety level. Based on technical and economic analysis, the safety level of some of the components can be adjusted.
Article 1.0.9 The damage of the structure can be divided into the following two types: 1. There is a warning damage. There is obvious deformation or other warnings before the damage, such as ductile damage of components.
2. Failure without warning. There are no obvious warning signs before the damage, such as brittle failure of components. For structures with no warning signs, the target reliability index should be higher than that of structures with warning signs.
Article 1.0.10 In order to ensure that the port engineering structure has the specified reliability, quality control should be carried out for investigation, observation, design, testing, raw material performance, product manufacturing and installation, use and maintenance, etc. The specific requirements are stipulated by the relevant specifications.
