摘　　要：为了有效保障施工安全、提高施工质量,以轨道交通建设项目为例,设计了一种深基坑排桩及钢混内支撑施工技术。在分析工程概况后,根据深基坑结构及支撑需要,设计轨道交通地下深基坑支护结构。然后设计并采用钻孔灌注桩施工、排桩与止水帷幕施工、内支撑施工的相关技术。根据测试结果可知:新技术可将各位置测点的水平和竖向位移控制在标准范围内。In order to effectively ensure construction safety and improve construction quality,taking a rail transit construction project as an example,a construction technology of deep foundation pit row piles and steel concrete internal support was designed.After analyzing the general situation of the project,according to the deep foundation pit structure and support needs,the supporting structure of the rail transit underground deep foundation pit was designed.Then,designed the relevant technologies of bored pile construction,row pile and water curtain construction,and internal support construction.According to the test results,the new technology could control the horizontal and vertical displacement of each measuring point within the standard range.
