| 摘 要： | 结合深圳市星海阁办公楼的工程实例,从周边环境对深基坑支护的特殊要求及复杂的地质条件出发,论述了采用土钉与锚杆联合支护形式的依据.介绍了在深基坑支护施工中采取的具体措施后期效果.同时分析了这种联合支护结构形式的力学特点,通过将两者联合使用,可实现锚杆支护结构水平侧移小和土钉支护结构受力合理的优点.且土钉与锚杆联合支护,使得上部锚杆和中下部的土钉墙两者形成了统一的受力整体,共同抵抗荷载和变形.

| Abstract: | The theory foundation of combined supporting by soil nailing and anchored bar has been discussed based on special environmental requirements for deep excavation supporting and complicated geological conditions, with the case of Shenzhen Xinghaige office building. Late effects of measures used in the course of constructing of deep excavation supporting has been introduced, and mechanics characteristics of this kind of combined supporting also have been introduced in the paper. Horizontal displacement of pres-tressed anchored bar is small and strength structure of soil nailing is reasonable. Combined supporting can make advantage of both prestressed anchored bar and soil nailing wall. Top prestressed anchored bar and middle and bottom soil nailing constitute a strong structure to resist load and distortion. |
