A discussion of the Prandlt calculation formula for anti-uplift stability of the bottom of a foundation pit wall in deep soft soil areas

Shuiwen dizhi gongcheng dizhi, 2021
The Prandlt formula is often used to calculate the anti-uplift stability of foundation pits in deep soft soil areas, which often fails to meet the specification requirements and brings great confusion to the design of foundation pit support. Based on the

Influences of excavation of deep foundation pits on deformation of adjacent double-line subway tunnels through measurement analysis

Yantu gongcheng xuebao, 2023
The excavation and unloading of foundation pits will lead to the deformations of the surrounding soil and the adjacent subway tunnels. The excessive deformation will seriously endanger the safe operation of subway tunnels.
