| 摘 要： | 周边环境复杂且需超深止水的深基坑围护结构大多采用地下连续墙围护体系，但由于其需重型机械设备施工且周期较长，对于施工现场场地条件局促、工期紧的工程项目，则无法适用。TRD-排桩工法围护体系可弥补地下连续墙围护体系局限性。本文依托工程实例对TRD-排桩工法围护体系的施工技术、变形控制效果和技术经济性进行研究。

| Abstract: | Most deep foundation pits with complex surrounding environment and extra deep preventing water curtain adopt underground diaphragm walls as enclosure. However, for some projects with limited environmental conditions and tight construction schedules, it is not applicable. Therefor, TRD row pile construction method has been applied as the retaining structure of deep foundation pit. Based on engineering examples, this paper conducts study on the construction technology, deformation control and technical economy of the TRD row pile construction method. |
