深基坑侧穿高架桥桥台的施工技术

Construction technologies of deep foundation lateral-crossing overpass abutment

结合某深基坑侧穿高架桥桥台的工程实例,分析了基坑降水、开挖对桥台的影响,提出了减弱深基坑施工对桥台不利影响的工程措施,并根据现场监测资料,总结出了深基础施工对桥台影响的基本规律。

Combining with the deep foundation lateral-crossing overpass abutment engineering example,the paper analyzes the impact of foundation dewatering and excavation upon abutment,and puts forward measures of reducing negative influence of the deep foundation construction upon abutment. According to in-situ monitoring data,it summarizes basis influencing law of deep foundation construction upon the abutment.
