The construction methods and technologies provide experience for reference concerning the foundation construction in water and large - span continuous rigid frame bridge ' s construction 文中介绍的施工方法和施工工艺,对于水上基础的施工和大跨度连续刚构桥的悬灌施工提供了经验和借鉴。
In this thesis , the main bridge of huanghe highway bridge in sanmenxia is taken as the engineering background , and the application of seismic isolation technology in the continuous rigid frame bridges is discussed 本文以某黄河公路大桥主桥为工程背景,研究连续刚构桥中的隔震技术。
Since the prestressed continuous rigid frame bridges were introduce to be builted in our country , through years , the achievment of the design and reaserch on bridge model is great 自预应力连续刚构桥引入我国以来,经过十多年的应用,在这种桥型的设计及研究方面已经取得了令人瞩目的成就。
It has become to pass that the permanent load - bearing capacity of the large - span pc ( prestressed concrete ) continuous rigid frame bridge constructed with the cantilever site cast construction method keeps cutting down in service 采用悬臂浇筑施工法施工的大跨pc连续刚构桥,在使用中其持久承载力不断地降低已成为事实。
The light of upper structure of continuous rigid frame bridge has been discussed in the paper . 5 . the method of closure of beam and control of elevation has also been analyzed in details 讨论了连续刚构桥施工监控的方法,对标高控制原理和参数修正作了分析,对连续刚构桥合拢的重要性、施工工序及配重问题进行了详尽的阐述。
