 1. "unified standard for reliability design for highway engineering structures"

 
According to the standards of "engineering structural reliability design uniform preparation" (GB 50153-2008) principles and requirements, give full consideration to the actual highway engineering, absorbed the related research results of reliability of Highway Engineering in recent years, puts forward the design of highway engineering structures of life, into the tunnel, and the design theory of engineering structural reliability of highway the perfect, this standard has an important guiding significance for guiding the revision of design specification. The standard has been submitted for approval in 2013.
 
 
 
2. "design method for design of highway special structure bridge"
 
Aiming at the design contents, design depth, design details, data collection and application, general design requirements and design contents of the highway special structure, the design documents are standardized. The project has compiled professional technicians and many expert consultants in our hospital, which fully embodies our technological progress and experience in bridge design for many years. At present, a draft for approval has been formed.
 
 
 
3. general specification for the design of highway bridge and culvert
 
This revision combined with the development and requirements of the road and Bridge in China in recent years, and has carried out a more comprehensive improvement on the original standard. The revised contents mainly include: the modified load vehicle design of highway bridges and culverts; supplement and perfect the relevant provisions of the traffic engineering, durability, security and environmental protection; increase the overall design, operation and safety monitoring, structural risk assessment and other relevant provisions. The project is now completed and is expected to be completed in 2014.
 
 
 
4. "code for design of highway steel structure bridge"
 
In the domestic and foreign relevant industry standard research results and practical experience of comparative analysis and Research on the basis of full investigation, considering the bridge steel structure in recent years the domestic development situation and future trends and other related factors, the probability limit state design method based on partial coefficient expression, the current "highway bridge steel structure and wood structure design specification" (JTJ 025-86) of supplements and amendments to increase the fatigue design load etc.. The project has been completed before the project.
 
 
 
5. "detailed rules for the design and construction of steel-concrete composite bridges"
 
 
As a recommended standard for the industry, based on the full research and practice of steel concrete bridge, the technical requirements for the design and construction of steel and concrete bridges and the best values of various indicators are proposed. Fully considering the current development level of science and technology, and actively absorb new technologies and methods that are technically mature, economically reasonable and conducive to environmental protection, reflect the development and achievements of steel concrete composite bridges in the past 20 years. The project has been completed before the project.
 
 
 
6. "guide to design of collision and collision avoidance for highway bridges"
 
This guide aims to better solve the problem of bridge collision safety and provide the basis for bridge designers. This guide is in accordance with the general principle of "Echelon fortification, multi-level security", introduced into resistance design method based on performance, formed a comprehensive system of bridge anti-collision anti-collision design system. The compilation of the guide is of great significance for reducing the probability of risk and the loss of impact. The guide has been submitted for review and is expected to be completed in 2015.
 
 
 
7. "highway suspension bridge design rules"
 
The rules fully absorb China nearly ten years of highway suspension bridge construction experience; fully implement the design concept of the life, and the limit state design method with partial coefficient expression, formed a design theory system consistent with industry standard. After the promulgation and implementation, it has an important role in promoting the overall level of the design of the highway suspension bridge in China. The rules have been submitted for approval in 2013.
 
 
 
8. code for design of highway reinforced concrete and prestressed concrete bridge and culvert
 
The code is a revision task issued by the Ministry of transportation and transport in 2011, and is now completed and reviewed. The regulation of the normal section of reinforced concrete bridges and culverts with circular section compression member grade, the bearing capacity calculation method of highway concrete bridge checking requirements - bearing box girder bridge, anti overturning checking requirements for complex bridge practical fine analysis method, the design method of external prestressed bridge, concrete bridge D the design method, improve the durability of the concrete bridge design method and construction requirements.
9. "road engineering terminology standard"
 
The revision of this standard combined with the latest development of highways, urban roads and other roads, increased the basic terms used in recent years, amended the original entries, and cut down less commonly used old terms. The revised standard total income of about 950. The project is now completed and is expected to be completed in 2014.
 
 
 
10. "road engineering drawing standard"
 
In order to adapt to the change and development of the drawing technology in the background of the development of China's highway construction in recent years, with the revision of highway engineering for many years design experience of our company and related industry standards in recent years, according to the Ministry of construction requirements, our company in the revision of the national standard, has completed the delivery reviewers.
 
 
 
11. "code for design of factories and Mines Road"
 
This specification is a recompiling task issued by the Ministry of housing and urban and rural construction in 2009, and has completed the work of sending and reviewing the manuscript. The regulation of some technical indexes route, improve the alignment requirements; modify the resilient modulus of subgrade, roadbed compaction, roadbed slope form and slope requirements; improve the pavement structure design requirements, modify the calculation method under heavy load pavement thickness; improve the requirements of bridge design.
