摘要
为了探讨临时便桥的类型和结构,以满足建设需求和适应场地需要,基于现有临时便桥资料,在总结临时便桥的设计原则和结构类型的基础上,以西部地区安临高速公路AL4标的2种临时便桥为例,对临时钢便桥和管涵式便桥的设计、施工和工程造价进行了对比分析,提出因地制宜的便桥方案。2种临时便桥自建成使用,经过了1个雨季洪水冲刷期,仍能保持整体结构的完整性,表明2种便桥在安临公路成功应用的适宜性。
In order to explore the types and structures of temporary bridges to meet the construction needs and the needs of the site,the design principles and structural types of temporary bridges are summarized on the basis of collecting and analyzing the existing temporary bridge data.On this basis,taking the application of two temporary temporary bridges in AL4 bid of Anlin expressway of Western China as an example,the project cost,respective characteristics and construction technology of temporary steel bridge and pipe culvert bridge are compared and analyzed,and the temporary bridge is put forward.Since the temporary bridge was built and put into use,it can maintain the integrity of the overall structure after a rainy season flood scouring period.This shows the applicability of the two temporary bridges applied in Anlin highway.
