Abstract:

The settlement of foundation in a heap of the ore-port is calculated by specification and one-dimensional consolidation theory. Based on settlement data measured in field，compressibility modulus and consolidation coefficient of soil layers are obtained by back analysis method. Post settlement is also calculated and predicted with the proved compressibility modulus and consolidation coefficient of soils, then the time and quantity of the next-stage loading is obtained. By contrast with traditional methods predicting settlement, the result is much more reliable, this method is good at reflecting mechanics of consolidation of soils. The method can provide references for design and construction of other such project.

Key words: compressibility modulus, consolidation coefficient, settlement, back analysis
