摘要
为使深基坑在拆除内支撑后基坑侧壁安全稳定,结合某工程案例探讨了换撑施工技术的实施要点:在外墙和基坑侧壁间采用混凝土板带作为穿楼板带;在后浇带、悬臂墙板等部位采用型钢作为传力带,基坑侧壁的应力通过上述传力带传递到结构实体,最终传递到对面基坑侧壁上,使基坑对面的应力相互抵消,从而保证基坑侧壁稳定。
In order to ensure the safety and stability of the deep foundation pit after the excavation of the deep foundation pit, the key points of the construction technology are discussed in combination with a project case. Between the external wall and the foundation pit side wall, the concrete slab is used as a floor strip. In the post-pouring, cantilever wall and other parts, the steel is used as a load transferring strip, the stress of the sidewall of the foundation pit is transmitted to the structural entity through the above-mentioned force band, and ultimately to the sidewall of the opposite foundation pit, making the stress across the foundation pit offset each other, so as to ensure the sidewall stability of the foundation pit.
