Determination of soil deformation and strength properties is great importance in geotechnical design. The disturbance that occurred during the sampling from field affects results obtained by laboratory tests. Therefore, lack representation conditions in-situ features with tests leads designers to carry out Standard penetration test (SPT) Menard pressuremeter (PMT) are most widely used which uti...

The assessment of pile drivability is the premise successful installation, and completely weathered (CW) rock may bring risk refusal. This paper presents a case driving refusal that occurred in CW gneiss layer. physical mechanical properties are analyzed based on results laboratory test, cone penetration test (CPT), standard (SPT). By comparing with those from intact gneiss, layer this study wa...

It has now been well established that the depth of bedrock is a key parameter in assessing the impact of local site conditions on seismic hazard analysis. Where conventional geotechnical testing like standard penetration test (SPT) or cone penetration test (CPT) requires a far greater cost and manpower to be used for such purposes, geophysical testing like ground-penetrating radar (GPR) and mul...

This study focuses on establishing a robust relationship between Standard Penetration Test-N values (SPT-N), geotechnical parameters and unconfined compressive strength (qu) using regression analysis. The proposed offers reliable method for estimating qu based SPT-N values. A comprehensive dataset comprising approximately 200 soil samples collected from various boreholes across Dhaka city was u...

Bangladesh is one of the world's most disaster-prone areas. The northwest region seismically active region. Dinajpur district closest to Himalayan frontal thrust, making it vulnerable earthquake-related liquefaction. Therefore, in-situ parameters are used assess liquefaction susceptibility subsurface geology for in terms soil safety factor (FS), potential index (LPI), and probability (PL). This...

Soil liquefaction resistance evaluation is an important site investigation for seismically active areas. To minimize the loss of life and property, hazard analysis a prerequisite seismic risk management. Liquefaction potential index (LPI) widely used to determine severity quantitatively spatially. LPI estimated from factor safety that ratio cyclic (CRR) stress calculated applying simplified pro...

Structural failure has been recently happenings mostly in the commercially populated states along coastal line Nigeria. As a result, an open field at chosen location Abuja, Nigeria, was investigated. For purpose of this study, test bores were drilled and Standard Penetration Tests (SPT) conducted every 1.5 m interval up to maximum depth 12.0 with bearing pressure ranging between 20 kN/m2 1000 ....

The work is a primary approach to grab attention on probability of liquefaction hazard in Rangpur City Corporation area. The investigated area of Rangpur was suspected to have high liquefaction potential since the foundation soil consists of loose sandy silt with a very shallow aquifer. Standard Penetration Test (SPT), which follows the general format of the Seed-Idriss simplified procedure for...

Shear wave velocities (Vs) and the number of blows SPT (N) are parameters that generally recorded in a geotechnical exploration campaign, literature there several publications on empirical correlations between N y Vs different types soil, first studies being attributed to Japanese researchers 60s 70s. North Peruvian pipeline was built recent quaternary eolian deposit, so research area Olmos nea...
