Determination of Geotechnical Properties in Intermediate Geo-Materials with Newly Developed In Situ Test Device
Publication: Geo-Congress 2023
ABSTRACT
Intermediate geomaterials (IGMs) are used as bearing strata in various civil engineering projects. It is important to reliably evaluate the geotechnical characteristics of IGMs to ensure the stability of their associated structures. In the case of IGMs, such as highly or completely weathered rocks and residual soils, it is difficult to obtain undisturbed specimens for laboratory tests. Therefore, field tests are performed to evaluate the design parameters of IGMs. However, it should be noted that conventional field tests are specialized for soils and rocks. In this study, a novel field test device, the borehole pressure shear tester (BPST), was developed to reliably evaluate the deformation and shear strength parameters of IGMs. A 1:1 scale physical model test was conducted to validate the reliability and applicability of the BPST. The test was performed using a calibration chamber, for simulating the stress conditions of the field ground. The test results were compared with laboratory triaxial compression test results and direct shear test results.
