Abstract

Abstract

Discussing the reason for the formula to calculate ground subsidence is corrected by feedwater percentage (μ)in the cohesive soil for the dewatering of pit,putting forward the specific methods and theoretical formulae of the subsidence calculation for building and its different sites away from pit.
- holing ratio of porosity,
- feedwater percentage,
- calculating point,
- curve of infiltration
