| 摘 要： | 软土地基下基坑土方开挖分三层开挖(-4.00 m、-8.60 m、-10.25 m),每层均先开挖四角区域,再开挖中间对撑区域,水平混凝土支撑安装穿插于开挖过程中,形成“中心岛式”,以及时平衡基坑外侧土压力,同时采用井点降水,改善土体的抗剪强度,并及时进行监测,进而达到基坑安全的目的。 |
| 关 键 词： | 深基坑 混凝土支撑 土方开挖 |

| Abstract: | The earthwork excavation of the foundation pit project was excavated with 3 layess with depths of-4.00 m,-8.60 m,and-10.25 m respectively.Each layer was excavated in its four angles' areas preliminarily and then in its central area with horizontal bracing fixed during the excavation process,in order to timely balance the pressure of the exterior soil of the foundation pit,and meanwhile point dewatering was adopted,so as to improve the shear strength of the soil mass to further protect the foundation pit's safety. |
| Keywords: | deep foundation pit concrete support earthwork excavation |
