For this edition he also reorganizes the material--for example splitting the chapter on allowable bearing capacity of shallow foundations into two chapters: one on estimating vertical stress due to superimposed loading, and the other on elastic and consolidation settlement
of shallow foundations.
Consolidation settlement reduces between 11% to 64% for sand content varying from 5% to 25%.
Immediate settlement is analyzed by using three methods, Timoshenko and Goodier's method, Janbu's method and Schmertmann's method for sand while consolidation settlement is used for the estimation of the settlement of clay layer.
Table 3 gives the settlement values determined by consolidation settlement method for clay only.
When settlement reaches design consolidation settlement
, the surcharge load can be removed.
Other topics include estimating the elastic and consolidation settlement
of foundations, dynamic bearing capacity and the associated settlement, materials and techniques for reinforcing foundations, and estimating ultimate uplift capacity.
Consolidation settlement is decrease in voids volume as porewater is squeezed out of soil, occurs slowly according to permeability.
In such cases empirical correlations will be very useful to estimate consolidation settlement of shallow foundations.
Chapter 9 One-Dimensional Consolidation Settlement
of Fine-Grained Soils.
The action comes on the heels of a vote yesterday by the Rhode Island Public Utilities Commission to approve the proposed rate consolidation settlement
filed by NEES subsidiary, The Narragansett Electric Company, and EUA subsidiaries Blackstone Valley Electric Company and Newport Electric Company.
The Rhode Island Public Utilities Commission voted today to approve the proposed rate consolidation settlement
filed by The Narragansett Electric Company, a subsidiary of New England Electric System (NEES) (NYSE:NES); and Blackstone Valley Electric Company and Newport Electric Corporation, subsidiaries of Eastern Utilities Associates (EUA) (NYSE:EUA), according to NEES President and Chief Executive Officer Rick Sergel.
