摘　　要：研究以珠江三角洲水资源配置工程为例,分析盾构操作层预应力梁、UHPC板吊装施工力学参数,以实际荷载为标准对设备进行选型,支腿反力计算、支腿最大压力计算获得地基承载力最低要求,并在土的重度15 kN/m,粘聚力c为25 kPa,内摩擦角为8°的条件下,校验地基承载力是否满足要求。Taking the the Pearl River Delta Water Resources Allocation Project as an example,this study analyzes the mechanical parameters of the prestressed beam and UHPC slab hoisting construction of the shield operation layer,selects the equipment based on the actual load,calculates the leg reaction force and the maximum pressure of the leg to obtain the minimum requirements for the foundation bearing capacity,and verifies whether the foundation bearing capacity meets the requirements under the conditions of the soil weight of 15 kN/m,cohesion=25 kPa,and internal friction angle=8°.
