Direct shear test- Procedure, Calculation, and drawback of direct shear test

Direct shear test- Procedure, Calculation, and drawback of direct shear test

What is the direct shear test and why it is required? Shearing strength of the soil is the magnitude of maximum shearing resistance offered by the soil when subjected to shear stress. The friction and interlocking of soil particles cause shearing resistance in soil. This Shearing resistance between soil may be due to chemical bonding …

Tacheometric Surveying – Purpose, Procedure, and Formula .PDF

Tacheometric Surveying

What is tacheometric surveying? Tacheometry surveying is defined as the branch of surveying in which horizontal and vertical distances between stations are determined from instrumental observations. In this method, no tape or a chain is used for measuring horizontal distances. This method is very rapid and convenient. The instrument which is used for tacheometric purposes …
