On August 3rd, 2007, at around 6: 45/kloc-0, Tuojiang Bridge in Xidi County, Hunan Province collapsed, resulting in 64 deaths, 4 serious injuries and 18 minor injuries, resulting in a direct economic loss of 39.747 million yuan.
(1) Basic information
Xidi Tuojiang Bridge is an important control project in the construction project of Fengda Highway from Fenghuang County, Hunan Province to Daxing Airport in Tongren, Guizhou Province. The total length of the bridge is 328.45m, the deck width is 1.3m, and the longitudinal slope is 3%. The bridge type is an open-web articulated arch bridge with four holes and a span of 65 m. The pier of this bridge is 33m high and is a multi-arch stone arch bridge. In June 2003, Hunan Provincial Communications Department approved the preliminary design of Fengda Highway Project, and in February of the same year, it approved the commencement report of Fengda Highway Project. Xidi Tuojiang Bridge started on March 12, 2004, and the planned construction period is 16 months. At the time of the accident, the laying of the arch ring and side wall of the bridge and the filling on the arch have been basically completed, and the dismantling work is coming to an end. The construction of the bridge is planned to be completed by the end of August, 2007, and completed and opened to traffic on September 20th, as a gift for the 50th anniversary celebration of Xiangxi Autonomous Prefecture.
The construction unit Fengda Highway Construction Co., Ltd. (hereinafter referred to as "Fengda Company") is a wholly state-owned company under the Xiangxi Autonomous Prefecture People's Government. The design and geological survey unit, Hua Gang Design Institute, is owned by the whole people and belongs to Changsha University of Science and Technology. The Institute has Grade A engineering design certificate, Grade A engineering consulting qualification certificate and Grade A engineering survey certificate in highway industry.
Hunan Luqiao Construction Group Corporation (hereinafter referred to as "Luqiao Company"). Is a wholly state-owned large-scale enterprise, with 28 subsidiaries and shareholding companies (units) under its jurisdiction. It has the qualification certificate of construction enterprise issued by the Ministry of Construction, and obtained the safety production license in July 2006. Luqiao Company implements a three-level management system, and the second-level organization Luqiao No.7 Company is responsible for the specific construction tasks of Xidi Tuojiang Bridge.
Supervision unit: Hunan Jinqu Traffic Consulting and Supervision Co., Ltd. is a limited liability company held by 45 natural person shareholders. With Grade A supervision qualification of highway engineering.
(2) The cause of the accident
1. The direct cause of the accident
Because the masonry materials of the main arch ring of the bridge do not meet the specifications and design requirements, the construction technology of the upper structure of the arch bridge is unreasonable, and the masonry quality of the main arch ring is poor, which reduces the integrity and strength of the arch ring masonry. With the increasing load on the arch, the masonry strength of the main arch ring near No.0 abutment 1 hole is about 3 to 4 meters wide, that is, the lower arch foot section of No.2 abdominal arch reaches the failure limit and collapses, and the whole bridge collapses rapidly due to the multi-arch effect.
2. The main cause of the accident
First, the project management department of Xituojiang Bridge, Fengdagong Dike, Seventh Road Company of Luqiao Company, the construction unit, changed the original main arch ring construction scheme without authorization, and the site management was chaotic, and the main arch ring construction did not meet the specification requirements. When the main arch ring fails to reach the design strength, it begins to take off the frame. Second, the project management of the construction unit Fengda Highway Construction Co., Ltd. (hereinafter referred to as "Fengda Company") is chaotic, failing to seriously urge the construction unit to rectify the construction quality problems found, changing the original design and construction scheme of the main arch ring with the construction unit without the consent of the design unit, blindly reversing the construction period to catch up with the progress, exceeding the authority, and even asking the supervisor not to go to the bridge for inspection. Third, Hunan Jinqu Traffic Consulting and Supervision Co., Ltd., the engineering supervision unit, failed to stop the construction unit from changing the original construction plan of the main arch ring without authorization, and failed to urge the rectification of the construction quality problems found in the main arch ring. When the main arch ring is completed but the strength data is not measured, it has been signed for acceptance. Fourth, Huaying Design Institute, the design and geological survey unit, subcontracted the survey project to individuals in violation of regulations, and the depth of geological survey design was not enough, and the on-site service and design disclosure were not in place. Fifth, the traffic quality supervision departments in Hunan Province and Xiangxi Prefecture have seriously neglected the quality supervision of the bridge project. Sixth, Xiangxi Autonomous Prefecture, Fenghuang County Government and relevant departments of Hunan Province failed to supervise the project approval, bidding, quality and safety production. The state government requested a blind deadline to present a gift to the 50th anniversary of the "State Celebration".
After investigation, it was found that this was a liability accident.
