调坡顶升技术在竖曲线段高架桥改造中的应用

摘要:

随着我国经济的迅速发展以及城市区域外围扩展,早期建设的城市高架桥在部分地段已经不能满足城市发展、更新的需求,高架桥梁改造采用调坡顶升先进技术是一种发展趋势和潮流,有着更为宽广的应用场景。文章通过对某高架桥改造工程的实例分析,介绍高架桥梁调坡顶升的总体设计思路、桥梁上下部结构顶升改造的关键技术问题,并提出了相关解决方案,对以后类似工程具有参考意义。

Abstract:

With the rapid development of China"s economy and the expansion of the periphery of urban areas, the early urban viaducts can no longer meet the needs of urban development and renewal in some sections. The adoption of advanced technology of slope adjustment and jacking for the transformation of viaducts is a development trend and trend, which has a broader application scenario. Through the analysis of an example of a viaduct reconstruction project, this paper introduces the overall design idea of the viaduct slope adjustment and jacking, the key technical problems of the bridge upper and lower structure jacking, and puts forward relevant solutions, which has reference significance for similar projects in the future.
