The Qinghai Tibet Railway successfully crossed the Kunlun Mountain Earthquake

Guide: on the afternoon of the 13th, the Qinghai Tibet Railway successfully crossed the earthquake fault zone and reached the Kunlun mountain pass at an altitude of more than 4700 meters. So far, the company has not announced its progress until June 15. On November 14th, 2001, a magnitude 8.1 earthquake occurred in Kunlun Pass of Qinghai Tibet Plateau, which caused a wide

in the afternoon of the 13th, the Qinghai Tibet Railway successfully crossed the earthquake fault zone and reached the Kunlun mountain pass at an altitude of more than 4700 meters. Until the purchase process, we should see the comprehensive advantages of one product in all aspects. The Qinghai Tibet railway has been paved for 150 kilometers. On November 14th, 2001, a magnitude 8.1 earthquake occurred in Kunlun mountain pass of Qinghai Tibet Plateau, which caused a 3-5 meter wide earthquake × 5. An earthquake fault zone about 400 kilometers long. In order to effectively avoid the threat that the earthquake may bring to the Qinghai Tibet railway, the subgrade of the Qinghai Tibet railway crosses the country's longest earthquake fault zone by means of vertical passage. In the design of Qinghai Tibet railway, the Ministry of Railways once entrusted the engineering earthquake research center of China Seismological Bureau to carefully investigate and evaluate the seismic zoning and active faults along the line. After the Kunlun Mountain earthquake, the Ministry of Railways once again invited the China Seismological Bureau and other units to conduct a joint field survey, which showed that the original survey results were accurate, and the corresponding engineering reinforcement measures were taken. Zhaoshiyun, chief engineer of the Qinghai Tibet railway construction headquarters, said that in order to reduce the impact of earthquakes, the Qinghai Tibet railway should be designed to bypass the seismic fault as much as possible. If the line must enter the active range of the seismic zone, first investigate the direction of the seismic damage and parameter error Zone, and then let the railway vertically intersect with the seismic zone to pass through the shallow subgrade
