摘　　要：超高层房屋建设时,通常会存在地下结构施工,其中,基坑开挖中最为重要的是电梯井、集水井等深坑结构的开挖,其开挖速度决定了结构的施工速度。采用槽钢支护法不仅避免了放坡开挖对原状土层的扰动,还提高了施工效率,是一种较为实用的深坑开挖方法。In the construction of super high-rise buildings,there are often underground structure construction.Among them,the most important excavation in foundation pit excavation is the excavation of deep pit structure such as elevator shaft and water collection well,whose excavation speed determines the construction speed of structure.The channel steel support method not only avoids the disturbance of excavation to the original soil layer,but also improves the construction efficiency.It is a practical method for excavation of deep pit.
