混凝土连续梁桥整体顶升施工技术及投资分析

Integral Jacking up Construction Technology and Investment Analysis of Concrete Continuous Beam Bridge

新建青荣城际铁路在某处下穿1座既有公路桥,该公路桥的净空高度满足不了青荣城际铁路的运营要求,为节省投资,需对该桥梁进行整体顶升改造。此文针对工程实际情况,阐述对该公路桥梁的整体顶升实施方案,以及进行整体顶升采用的主要施工工序和工艺。并对其所需投资进行分析。可为类似工程提供借鉴。

The new - built Qingdao - Rongcheng intercity railway across under the existing highway bridge. The clearance of highway bridge can not meet operation requirements of intercity railways. In order to save investment, it is necessary to carry on the integral jacking up for the highway bridge. According to the actual situation of the project, the implementation scheme, main construction process and technology of integral jacking up for the highway bridge is expounded in this paper. And the investment of the project is analyzed. The research results can provide reference for similar projects.
