场地受限情况下跨线桥梁的施工技术研究
|
摘要
文章以广西柳南高速公路为例,着重对场地受限情况下的跨线桥梁施工技术进行了分析研究,提出了连续旋体梁施工模型,并通过特定试验结果来对比、分析和验证所提出的连续旋体梁施工模型的正确性与可行性。此外,针对广西刘楠高速公路上的部分特殊桥梁结构,文章引入了空间架构的受限跨线桥梁施工方案,通过对比得知,连续旋体梁以及空间架构梁在受限情况下的跨线桥梁施工领域中均有较好的作用。
With Liunan Expressway in Guangxi as the example,this article analyzed and studied the construction technology of cross-line bridges under the site limitations,proposed the continuous revolving beam construction model,and then compared,analyzed,and verified the correctness and feasibility of continuous revolving beam construction model through specific test results,in addition,aiming at some special bridge structure on Liunan line,it introduced the construction scheme of limited cross-line bridge of space structure,and through the comparison,it found that the continuous revolving beam and space frame beams have a better effect in cross-line bridge construction field under the limitations.
