... in terms of their accuracy and heterogeneity. A soft loading plate was made by 3D-printing in order to avoid the singularity of the stress at the edge of the concentrated load. When the estimation based on a concentrated load test with a single specimen was not satisfactory, the Brazilian test of a sample...

... between these pairs are anticipated. The main objective of this study is to identify the relationship between the unconfined compressive strength and the axial point load test as well as the relationship between the indirect tensile strength and the diametral point load for the shale, clay stone...

... these experiments the size effect equation is similar in format to Eq. (1). This paper discusses the results from various published experimental programs and compares them to the Hoek and Brown equation. The results from UCS and point load tests conducted on two different granites and a marble at different sizes...

... are available to estimate the bearing capacity of a pile. Pile load test is the most accurate method to evaluate the pile bearing capacity[1]. In this study, one set with one instrumented compression (CP) and one tension (TP) pile load tests was conducted to investigate the he load transfer behavior...

... ABSTRACT: Drilled shafts socketed into rock have been widely used as a foundation system for bridges, retaining structures, and slope stabilization, to resist both vertical and lateral loads. A review of literature suggests that only very few existing field lateral load tests data...

... and deformations predicted by the model were in good agreement with the results observed in the full-scale load tests. Conventional geotechnical explorations can provide sufficient data to estimate the RMR of rock. The load tests and model predictions indicate the RMR system allows the strength parameters...
