Recently, Zhongben Testing Authentication Co., Ltd. received a letter of thanks from the Cambodian branch of Shanghai Construction Group Co., Ltd., expressing its gratitude for overcoming difficulties and successfully completing tasks in the dynamic and static load test projects of the Bassa River Dongcha Bridge and the Mekong River Bridge in Cambodia.

　　The Dongcha Bridge of the Bassa River in Cambodia is located in Phnom Penh, Cambodia, across the Dongcha River of the Bassa River, 20 kilometers south of Phnom Penh. The layout of the entire bridge is 7 × 20+75+135+75+10 × 20m, divided into 5 pairs, with a total length of 630.04m. The upper structure of the third unit 75+135+75m is a prestressed concrete cast-in-place box beam, which adopts a cantilever pouring construction method. The other four units are all simply supported continuous hollow slabs on the bridge deck. The Mekong River Bridge Project (Cambodia 71C National Highway Phase I Project) is located 30 kilometers north of Kampong Cham province. It crosses the Mekong River and connects Costa County in Tboung Khmum province on the east bank and Chengdong County in Kampong Cham province on the west bank. The layout of the entire bridge is 6 × 30+6 × 50+75+3 × 135+75+3 × 30m, with a total bridge length of 1131m (including 6m of abutment length). The upper structure of the main bridge adopts 75+3 × 135+75m variable cross-section prestressed concrete continuous rigid frame composite system, with the main pier of the lower structure being a box pier body and the side pier being a solid pier body.

　　The dynamic and static load test project of Cambodia's Bassa River Dongcha Bridge and Mekong River Bridge is another load test project undertaken by the company in Cambodia. The on-site project team overcame such adverse factors as tight time, small staff, and difficult equipment allocation, and carefully planned and worked hard from the whole process of project scheme formulation, personnel organization, and on-site implementation to ensure the smooth implementation of the project and lay the foundation for the smooth opening of the project.
