Benefits of The Dilatometer Test

 

• Accurately measures the constrained deformation modulus of soil


• Accurately predicts settlement


• Knifes into the soil causing much less volumetric and shear strain to the soil than conical probes such as CPT or SPT


• Correlates well with the soil stress history


• Marchetti (1980) and Lutenegger (2006) undrained shear strength predictions of cohesive soil compare quite favorably with other measurements worldwide


• Schmertmann’s elastic half-space theoretic calculation using the thrust measurement accurately predicts the drained plane strain angle of internal friction for cohesionless soil


• Before and after measurements show how well ground improvement methods work


• True-interval seismic tests accurately and repeatedly measure the compression above water table and shear wave velocities


• Pore pressure dissipation tests in cohesive soil below water table measure time rate of consolidation

FAQ

Q: What is a flat dilatometer test?

A: The Flat dilatometer, or DMT, is an in-situ device used to determine the soil in-situ lateral stress and soil lateral stiffness and to estimate some other engineering properties of subsurface soils. It is a relatively simple test and its use in geotechnical investigations becomes more and more common.

Q: What is the purpose of a dilatometer test?

A: The Flat Dilatometer Test (DMT) is an in-situ testing method used to determine the strength and deformation characteristics of fine-grained soils. This method involves a stainless blade shaped probe with a thin circular steel membrane mounted on one side.

Q: How does a dilatometer work?

A: The optical dilatometer allows the monitoring of materials' expansions and contractions by using a non-contact method: optical group connected to a digital camera captures the images of the expanding/contracting specimen as function of the temperature with a resolution of about ±70 micrometre per pixel.

Q: What are the different types of dilatometers?

A: There are multiple types of dilatometer available, but the four most commonly known dilatometers are Capacitance Dilatometer, Connecting Rod or Push Rod Dilatometer, High Resolution-Laser Dilatometer, and Optical Dilatometer.

Q: What is a Flat Dilatometer Test Equipment?

A: A Flat Dilatometer Test (DMT) Equipment is a device used in geotechnical engineering to measure soil properties. It consists of a flat blade that is pushed into the ground and has a membrane on one side which can be expanded to measure soil pressure.

Q: How does the Flat Dilatometer blade penetrate the soil?

A: The blade is typically pushed into the soil using a hydraulic or mechanical jack. It is inserted slowly and steadily to ensure accurate readings.

Q: What soil properties can be determined using DMT Equipment?

A: It can determine soil type (e.g., sand, clay), soil modulus, overconsolidation ratio, and shear strength.

Q: How accurate are the measurements from DMT Equipment?

A: The accuracy depends on proper calibration and correct operation. Generally, with proper procedures, it can provide reasonably accurate measurements within a few percent error for soil modulus and other key properties.
