چکیده

This paper presents an interpretation technique to quantify the effects of compaction state and matric suction on undrained shear strength compacted clay under confined triaxial compression. novel is based mathematical frameworks SHANSEP (Stress History Normalized Soil Engineering Property) method for saturated soil BBM (Barcelona Basic model) unsaturated soil. Test data Calgary till were analyzed interpreted using proposed technique. The very useful in delineating relative impacts factors behavioral trends measured strength. It was found that addition initial void ratio suction, structure failure mode exert significant influence clay. attractive engineering practitioners because compression tests (with no pore air water pressure measurement) are much simpler less time consuming compared rigorous laboratory

Methods of interpretation of borehole falling-head tests performed in compacted clay liners

The interpretation of falling-head tests in cased boreholes is discussed. These tests are commonly used to measure hydraulic conductivity of compacted clay liners and are often part of the construction quality assurance program. Three methods of interpretation are reviewed with data sets collected from real tests. Two of these methods have been the subject of past research by other authors: the...

Mechanical properties of dewatered sewage sludge.

The mechanical properties of dewatered, anaerobically digested sewage sludge were determined from soil laboratory tests. The sludge material is largely composed of organic clay sized-particles, a sizable fraction of which is in an active state of biological digestion which can continue over many years under field conditions. Moderately digested sludge material was found to have a typical specif...
