高速公路桥梁施工中高墩施工技术应用探讨

Discussion on the Application of High Pier Construction Technology in Expressway Bridge Construction

在我国经济建设快速发展的推动下,高速公路建设已进入一个高峰期。在山区高速公路桥梁建设中,高墩占据了较大的比例。高墩的作用是将桥梁上部结构自重和二期荷载传递到基础,扮演着"承上启下"的重要角色。高墩的施工质量直接决定着桥梁的使用寿命、使用效果和养护成本。论文对高速公路桥梁高墩施工的特点及具体的技术应用进行了深入的探讨。

Driven by the rapid development of China’s economic construction, expressway construction has entered a peak period. In the construction of highway bridges in mountainous areas, high piers account for a large proportion. The function of high pier is to transfer the self weight and second stage load of bridge superstructure to the foundation, which plays an important role of "connecting the preceding and the following". The construction quality of high pier directly determines the service life, service effect and maintenance cost of the bridge. In this paper, the characteristics of high pier construction of expressway bridge and the specific technology application are studied.
