<p>Although many intact rock types can be very strong, a critical confining pressure can eventually be reached in triaxial testing, such that the Mohr shear strength envelope becomes horizontal. This critical state has recently been better defined, and correct ...

The application of suction on a saturated soil specimen consolidated in an oedometer may cause the lateral shrinkage. This study tries to simulate such situation using triaxial testing apparatus and to quantify the lateral deformation due to drying and shearing. ...

<p>Conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. In this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ...

Tire shreds and tire shred - soil mixtures can be used as alternative backfill material in many geotechnical applications. The reuse of tire shreds may not only address growing environmental and economic concerns, but also help solve geotechnical problems ...

Triaxial testing has been used for many years by geotechnical engineers, to monitor the response of soils to varying stress conditions. Similarly, Hot-Mix Asphalt (HMA) has been tested, using triaxial systems, to determine the reaction of the material to both ...

Failure in soils often means that one mass of soil begins sliding over another mass. The soil is said to fail in shear because the movement at the failure surface involves relative displacement parallel to the failure surface (Fig. 1). Several types of laboratory ...

<p>The results of studies of the initiation and propagation of fracture from a single Griffith crack in a biaxial compressive stress field are reported in this paper.</p>

<p>Unconfined compression tests are normally carried out on lime treated soft clays with variation of the additive content and curing time. These studies were valuable in having a good understanding on the strength of the treated clays. In this paper, some ...
