On the morning of August 29, 2017, the China Highway Society organized a meeting in Beijing on the 2017 project initiation group standard Road and Bridge Collision Avoidance, which was compiled by CCCC First Highway Engineering Design&Research Institute and participated by Xi'an CCCC Civil Engineering Technology Co., Ltd fender The review meeting of the outline of the Technical Conditions was held by Zhou Haitao, the former chief engineer of the Ministry of Transport, Li Yanwu, the former director of the Highway Bureau of the Ministry of Transport, Wang Wuqin, the former general manager of the Ministry of Communications Construction Technology, Zhao Junli, the deputy chief engineer of CCCC Highway Planning and Design Institute Co., Ltd., and Zeng Xianwujiao, a senior expert of CCCC Highway Planning and Design Institute Co., Ltd, Peng Zeyou, chief engineer of CCCC First Highway Engineering Co., Ltd. and Shi Chunjuan, engineer, reported the standard preparation outline on behalf of the preparation team.
The experts attending the meeting listened to the report of the preparation group, reviewed the standard outline and draft, and believed that the Technical Conditions for Collision Fenders of Highway Bridges formulated was necessary and timely, and had guiding significance for further improving the technical level of bridge anti-collision in China. The outline prepared was clear in guiding ideology, comprehensive in content, reasonable in chapter arrangement and division of labor of personnel, and feasible in implementation, It was unanimously agreed that the outline passed the review.
At present, the country strongly advocates and attaches importance to the preparation of group standards. In the future, the specific product standards of the transportation industry will be mainly undertaken by the society group standards. This standard is the first group standard for anti-collision of the China Highway Society. The formulation of this standard is conducive to filling the gap in the standards in the field of highway bridge anti-collision fenders, and standardizing the technical performance of bridge anti-collision fenders, It is of great significance to ensure the quality of its products, accelerate the research and transformation of technical achievements, and improve the overall technical level of bridge anti-collision in China for the technical support and standard guidance in the field of bridge anti-collision in China.
-------------Background information -------------
In recent years, ship collision accidents have occurred frequently and are on the rise. The adverse economic and social impact caused by ship collision cannot be ignored and has attracted the attention of all sectors of society. The latest major ship collision accident occurred during the typhoon "Tiange". At around 6:00 p.m. on August 23, 2017, a social ship was "blown" under the bridge by strong wind, After hitting the pier in the water of Guangdong Modaomen Bridge, it was jammed, causing the pier to be damaged, the bridge deck to sink 27cm, two-way traffic of the bridge was interrupted, and the entrance was completely closed.
In order to effectively solve the major traffic safety accidents caused by the collision between ships (or vehicles) and various building structures, the research on highway traffic safety protection technology was carried out, and a technical system was formed for the analysis of impact dynamics problems, the assessment of pier collision risk, and the design of pier safety protection devices
