沿海道路桥梁沉降实时监测研究

Study on Real-time Monitoring of Coastal Road and Bridge Settlement

沿海地区较特殊的工程环境和较高的建设要求,给该地区道路桥梁的施工及后期养护带来较大难题,同时使得该地区道路桥梁的沉降具有较大的研究意义。文章采用Asaoka法提出理论计算公式,以南宁吴圩机场第二高速项目平垌2号分离式立交桥为工程背景,进行实时沉降观测,通过对比观测数据与理论计算结果,得出南宁及周边地区道路桥梁的沉降规律,并提出相应的解决方法。

The special engineering environment and higher construction requirements in coastal areas bring great difficulties to the construction and post-maintenance of roads and bridges in such area,thus the settlement of roads and bridges in this area has great research significance.This article proposed the theoretical calculation formula by Asaoka method.Taking Pingdong 2#split overpass of Nanning Wuxu Airport Second Expressway project as the engineering background,it conducted the real-time settlement observation,then,by comparing the observed data with the theoretical calculation results,it obtained the settlement law of road and bridge in Nanning and surrounding areas,and proposed the corresponding solution.
