What is Box Sampling? Box Sampling is a soil and rock sampling method carried out by manually excavating a square or rectangular pit of a specific size. This technique is primarily used to collect bulk samples or disturbed samples from a targeted geological layer. Key Characteristics of the Box Sampling Method Applied at the surface […]
Introduction In geotechnical engineering, understanding the mechanical properties of rock is essential to ensure the stability of structures such as slopes, foundations, tunnels, and dams. One of the most fundamental mechanical parameters is Uniaxial Compressive Strength (UCS), which defines the maximum compressive stress a rock can withstand before failure. What is Uniaxial Compressive Strength (UCS)?
What is a Water Level Dip Meter? A Water Level Dip Meter is a precision instrument widely used in geotechnical and hydrogeological projects, especially for boreholes and groundwater monitoring. This tool uses a highly sensitive sensor that produces both a “dip” sound and a light signal when the probe touches the water surface. These signals
Introduction The Vane Shear Test (VST) is one of the most practical methods in geotechnical engineering to measure the shear strength of soft cohesive soils such as clay and silt. Engineers perform the test by inserting a vane-shaped tool into the soil and rotating it gradually until the soil fails in shear. Because of its
In geotechnical drilling activities, drilling machine guarding is a vital safety feature that is often overlooked. Its role goes beyond protecting the operator—it also safeguards equipment, improves efficiency, and ensures compliance with occupational safety regulations. Proper guarding is an essential part of a safe and reliable drilling operation. Ensuring Operator Safety Drilling machine guarding in
Hand Auger soil investigation is one of the most common and cost-effective techniques for shallow soil drilling. Engineers and researchers often use a hand auger, also known as a manual drill, to collect soil, sediment, and rock samples at limited depths. This method plays an important role in geotechnical engineering, agriculture, and environmental studies, especially
Water well drilling is a crucial technical process for accessing groundwater resources, which are widely used in agriculture, industry, and domestic needs. While it provides significant benefits, drilling activities also carry high safety risks for both workers and the surrounding environment. Therefore, implementing Occupational Health and Safety (OHS) standards is mandatory at every stage of
In geotechnical engineering, understanding soil behavior under dynamic loading is crucial, especially for large infrastructure projects such as bridges, dams, ports, and developments in earthquake-prone areas. One of the key laboratory methods to evaluate soil response to cyclic loading is the Cyclic Triaxial Test. This test provides essential data on soil dynamic resistance, liquefaction potential,
sumber gambar : www.utest.com.tr The Triaxial Test is one of the most common and accurate geotechnical methods used to determine the shear strength of soil. This test plays a crucial role in the design of foundations, slopes, embankments, and other structures that directly interact with soil conditions. There are three main types of triaxial tests:
A geotechnical laboratory plays a vital role in analyzing the physical and mechanical properties of soil and rock. These tests are crucial for foundation design, slope stability, and even mining planning. Below are some of the most common geotechnical laboratory testing equipment along with their functions: Triaxial Test Machine Function: Measures the shear strength of
