Module 1 : Site Exploration and Geotechnical Investigation
Lecture 2 : Boring Methods of Exploration [ Section 2.1 : Different Types of Boring Methods ]
Boring methods of exploration
The boring methods are used for exploration at greater depths where direct methods fail. These provide both disturbed as well as undisturbed samples depending upon the method of boring. In selecting the boring method for a particular job, consideration should be made for the following:
The materials to be encountered and the relative efficiency of the various boring methods in such materials.
The available facility and accuracy with which changes in the soil and ground water conditions can be determined.
Possible disturbance of the material to be sampled.
