Abstract :
Based on the ground settlement calculation method recommended by the Chinese national Standards(GB 50307-1999), according to the type of soil and soil physical properties (characteristics of porosity ratio, plastic limit, compression modulus), soil layer thickness and water drawdown, the ground settlement quantified board models are established. The established models provide a fast, direct ,simple and useful method and tool for land subsidence calculation in engineering construction.
