Abstract
Based on the newly-built continuous rigid frame bridge project of Songjiazhuangchuan extra-long bridge with a main bridge of (60+2í100+60) m on Heshun-Xingtai Railway, this paper fully verifies its scheme selection in perspective of bridge type and pier type, analyzes the key techniques for rigid frame design such as reasonable size of pier body, rigidity, dynamic property, jacking force, construction and bridge stability, summarizes a complete set of comprehensive and practical design concept and method, addresses the characteristics and applications of double-leg and thin-wall piers.关键词
