摘要
圆拱或连拱基坑支护结构能充分发挥拱形的空间效应,均匀受力时,截面只受压应力作用,可有效控制变形,确保基坑稳定。通过某基坑支护实例,阐述这一结构形式的实际应用。
The restaining wall of circle or continious arches, for supporting the excavation of foundation, can fully display the arch＇ s three-dimensional effect. When it undergoes even stress, its section only has compression stress, and this can guarantee the excavation of foundation to be under control and keep stable. Through the example of the design for an excavation of foundation, this article elaborates the practical application of this structural systle.
