Rapid determination of soil unconfined compressive

2021-3-9  Unconfined compressive strength (UCS) is one of the most important mechanical properties for evaluating the strength of adhesive soils in many engineering projects including forest roads. Measuring the USC of soil in the laboratory and in situ is difficult, time-consuming, and costly, so it is essential to explore a rapid, low-cost, and non-destructive method.

Estimation of Unconfined Uniaxial Compressive Strength

Unconfined Compressive Strength (UCS) of the rocks plays a significant role in geotechnical and rock engineering projects. Due to difficulties UCS estimation is done using indirect methods such as Schmidt Rebound Hammer (RN) and ltrasonic Pulse VUelocity (UPV) tests that are quick and inexpensive tests.

8. STRENGTH OF SOILS AND ROCKS

2009-2-23  For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and

2015-3-1  According the theory, E s is equal to the rock's compressive strength at perfect efficiency, but the energy for crushing rock is not sufficient when E s is much greater than σ 1. The main reasons for this phenomenon are improper drilling operation parameters or drilling problems such as bit balling, vibrations, bit bulling, and bottom-hole balling.

Design of the various pavement layers is very much dependent on the strength of the sub-grade soil over which they are going to be laid. Sub-grade strength is mostly expressed in terms of CBR (California Bearing Ratio). Weaker sub-grade essentially requires thicker layers whereas stronger sub-grade goes well with thinner pavement layers. The pavement and the sub-grade mutually must sustain the...
