In order to overcome many of the problems associated with the unconfined compression test, Broch and Franklin (1972) proposed a testing method called the Point Load Test. The test consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. The unconfined compressive strength (UCS) of stabilized soil with lime and cement is a crucial mechanical factor in developing accurate geomechanical models. In the past, determining UCS required laborious laboratory testing of core samples or complex well-log analysis, both of which consumed many resources. This study introduces a novel method for .

IS 1586 : 1968 Methodfor Rockwell hardness test (B and C scales) forsteel . IS 9179 : 1979 . Quick and accurate acquisition of the uniaxial compressive strength (UCS) of the surrounding rock at the tunnel face effectively ensures the safety of tunnel construction. This paper proposes a model for estimating the USC of the tunnel surrounding rock based on boreholes measurement-while-drilling data and stacking ensemble algorithm. Firstly, four .Method for Determining the Unconfined Compressive Strength of Intact Rock Core Specimens SC T 39 1. Scope This method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting .Unconfined compression test procedure and description for geotechnical testing . It provides a measures of the undrained strength and the stress-strain characteristics of the rock or soil. The unconfined compression test is often included in the laboratory testing program of geotechnical investigations, specially when dealing with rocks. .

It is costly, time-consuming, and difficult to measure unconfined compressive strength (UCS) using typical laboratory procedures, particularly when dealing with weak, extremely porous, and fractured rock. By efficiently choosing the variables from a subset of the dataset that includes the Schmidt hammer rebound number (SRn), bulk density (BD), bulk .Understanding the strength characteristics and deformation behaviour of the tunnel surrounding rock in a fault zone is significant for tunnel stability evaluation. In this study, a series of unconfined compression tests were conducted to investigate the mechanical characteristics and failure behaviour of completely weathered granite (CWG) from a fault zone, considering with .
The unconfined compression test is conventionally performed by applying axial load to a cylindrical specimen with a specific length to diameter ratio. Various arrangements have been developed to perform the unconfined compression tests as indicated in Fig. 1. The short cylindrical specimen represented as type 1 is in direct contact with the .
