The Casagrande method is a method for determining the initial consolidation pressure of soil samples. It is mainly used in geotechnical tests and is of great significance for the study of soil consolidation behavior.

Kinematic viscosity and dynamic viscosity are two different physical properties that describe the viscosity or flow properties of a liquid.

Soil compactor is a kind of construction equipment, which is divided into heavy-duty manual compactor and CNC multifunctional electric compactor. It is mainly used to determine the optimum moisture content and unit density of compacted soil, which is used as the basis for controlling soil moistur...

The artificial freezing method is used to make the frozen soil wall of the temporary enclosure structure. If the surrounding environment permits, it can be promoted and applied in deep foundation pit support. The application of the foundation pit frozen soil wall is basically not limited by the f...

Soil strength refers to the stress that causes soil damage, so to study soil strength, we must first understand its damage form. Since the strength of soil particles themselves is much greater than the bonding strength between particles, shear failure of soil under external force is an important ...

Soil has rheological properties, and its common rheological phenomena mainly include creep, relaxation, flow, strain rate effect and long-term strength effect. Usually, experimental models are used to study these rheological phenomena, reveal rheological laws, and establish corresponding theories...

Coarse-grained soil requires large-sized test instruments due to its large particle size. No matter how large the size is, it is limited, that is, for instruments, they all have their own applicable range. If the sample particle size is too large or the instrument size is too small, it is necessa...

The coarse-grained soil triaxial shear test is an important test for studying the mechanical properties of coarse-grained soil (such as crushed stone soil, gravel soil, etc.). In addition to the classification of fine-grained soil according to drainage conditions, the determination of the test ty...

The test indicators of soil include physical indicators (weight, water content, soil particle density, etc.) and mechanical indicators (shear strength, compression modulus, permeability coefficient, etc.). Soil sampling should be carried out during engineering geological survey, and specific data...

The engineering properties of soil are a comprehensive expression of its material composition and physical state, and its appearance characteristics are often closely related to the material composition. For example, the color of the soil seen from the outside reflects the composition and content...

Geotechnical triaxial instrument material flexibility, soil, water-reshaped soil and original soil, etc., soil deformation value is large, water absorption is strong, volume strain and Poisson's ratio, through saturated specimens, vertical pressure is applied, the pores are filled with water afte...

General triaxial test and true triaxial test are two commonly used test methods in geotechnical mechanics. Conventional triaxial apparatus consists of a pressure chamber, an axial loading system, a confining pressure control system, etc.
