摘 要:我国现有铁路规模无法满足快速增长的国民经济发展需要。近些年来,我国国民经济强劲增长带动了对国内交通运输基础设施的需求增长,铁路投资远远滞后,造成我国铁路运输密度非常高,运输周转量增长也大大超过了铁路运营长度的增长。“十一五”开始后,铁路投资出现了大幅增长。The scale of Chinese existing railway can not meet the demand for the rapid growth of economy. The strong growth of economy boosted the domestic need of transportation infrastructure, but the railway investment lagged far behind, which resulted in the utmost high density of China transport and the growth of transport volume also greatly exceeded the growth of the length of railway operations. Since 'Eleventh Five-Year Plan', railway investment has increased by leaps and bounds. The quantity of bridges accounts for a large proportion in the current design of high-speed railway .By learning from Japan, Korea, Taiwan and other neighboring countries or regions, plus independent research and development, Chinese technology of high-speed railway bridge construction has ranked on the top of the world. In China, the industry of high-speed railway bridge erecting equipments is emerging, coming into being with the development of China high-speed railway (including inter-city rail and passenger rail line) and achieving leap-forward development since 2006.
