桥梁基础深基坑施工技术总结

深基坑施工属于危险性较大的分部分项工程,在建(构)筑物密集的地区或者地下水丰富的地区,往往需要进行基坑支护,才能保证施工的安全和顺利,并减少对相邻建(构)筑物和管道管线的不利影响,因此,桥梁基础深基坑的开挖、支护、降水等方案应根据桥位所在的地质条件和周围环境来进行选择,并在施工过程中做好监测工作,文章对其施工及监测的技术要点进行分析和总结。

The construction of deep foundation pit is a dangerous partial project. Foundation pit support is often needed in areas with dense buildings or areas rich in groundwater, so as to ensure the safety and smooth construction and reduce the adverse effects on adjacent buildings and pipelines. The schemes of excavation, support and dewatering of the deep foundation pit of the bridge foundation should be selected according to the geological conditions and surrounding environment where the bridge is located, and the monitoring work should be done well in the process of construction. The technical key points of construction and monitoring are analyzed and summarized in this paper.
