• This paper is based on scientific research project on municipal construction of chengdu city " study on development and application of new technology on high strength concrete bridge with external prestress " , probes into structural behavior of concrete continuous beam with external prestress from several aspects as follows : 1 . design and finish static test of 4 continuous beams with external prestress that have different ppr
  本文主要结合成都市城建科研项目“体外预应力高强混凝土桥梁新技术的开发与应用研究”来进行，对体外预应力混凝土连续梁的结构行为进行了以下几方面的探讨： 1设计并完成了四片体外预应力连续梁的静载试验。试验梁采用不同预应力比率，以研究在不同预应力比率作用下的受力性能。
• It is one of primary reasons that people had no sufficient knowledge on constructural behavior of concrete beam with external prestress , and the application of the external prestressing technology was " " restraint . therefor , researchers of home and overseas have carried out a series of study on concrete beams with external prestress
  其主要原因之一是人们对体外预应力混凝土梁的结构行为没有足够的认识，阻碍了体外预应力技术的应用。为此国内外对体外预应力混凝土梁开展了一系列的研究。
• Reviewing study on concrete beams with external prestress home and overseas , we have found that these studies most deal with simple supported beam and rarely deal with continuous beam so as to people ' s knowledge of continuous concrete beam with external prestress is scanty . so it is necessary to do an in - depth study on continuous concrete beam with external prestress
  纵观国内外在体外预应力混凝土梁方面的研究，可以发现，绝大多数的研究集中在简支梁方面，而对于作为超静定结构的连续梁的研究很少，以至于人们对体外预应力混凝土连续梁的认识还不够充分，所以有必要对体外预应力混凝土连续梁进行深入的研究。
