沉井地压——一种特殊表土地压的探讨

Study on the Earth Pressure of Drop Shaft

分析探讨沉井在表土中下沉时所引起的受力现象及其相关的论点 ,发现沉井在正常下沉过程中 ,不仅仅会受到竖井表土地压的作用 ,更主要是沉井的前端 (刃脚 )

This paper deals with the force bearing problem of a drop shaft when it subsides in the surface soil. The author suggests that, when a drop shaft subsides in normal conditions, not only it bears the earth pressure of the pit but also suffers from the passive soil pressure on the foot blade of the drop shaft.
