Soil Mechanics and Engineering Geology
Австралия
Добавлен 12 июн 2020
I have taught soil mechanics, rock mechanics, geotechnical engineering practice, and engineering geology at Griffith University for over fourteen years. I make videos about fundamental soil and rock behaviour, geotechnical engineering, and how to solve relevant engineering problems. If you find these videos useful, please like and share them with your friends/colleagues and subscribe to my channel.
Soil Classification using USCS | Problems Solved #education
Soil is classified using the Unified Soil Classification System (USCS). The classification is based on the amount of fines and coarse-grained material (such as gravel and sand). Three examples are given: Soil A (0:28), coarse-grained material is classified based on the gradation. Soil B (5:39) and Soil C (8:20) are plastic soils and are classified based on their plasticity.

Brazilian Tensile Strength Test on Soft Rock | Rock Split in Half #education #engineering
Просмотров 27320 часов назад
Brazilian tensile strength conducted on soft sandstone. The rock size is 50 mm in diameter and 20 mm in width. The load is applied trough a frame using a conventional unconfined compression machine. The rock tensile strength was estimated as 1.7 MPa. #experiment #rock #geology
Soil Consolidation with Prefabricated Vertical Drains (PVDs) | Procedure Explained #education
Просмотров 166День назад
It may take a very long time to consolidate soft clay mass, which may not be acceptable during construction. Prefabricated vertical drains (PVDs) or wick drains can be used as an alternative solution that would significantly decrease the process of consolidation. This video explains how to estimate the time of consolidation when PVDs are installed in soil mass in a square or triangular pattern ...
Teacher Explains Soil Fraction Size Boundaries for Soil Classification #education
Просмотров 3732 месяца назад
Sieve test is conducted to classify soil. The Unified Soil Classification System (USCS) is based on the amount of coarse-grained and fine-grained fractions. There are the ASTM boundaries: 4.75 mm between gravel and sand; and 0.075 mm between sand and fines (which included silt and clay). This video explains the boundaries and shows what gravel, sand and fines look like. #science #engineering #e...
Rankine Active and Passive Pressures on Wall in Cohesive Soil Mass #education
Просмотров 6482 месяца назад
This video explains how to calculate the active pressure (0:10) and passive (7:40) pressure in cohesive soil mass. The active earth pressure tends to decrease with the increase of the soil cohesion, while the passive earth pressure increases with the increase of the soil cohesion. #geotechnicalengineering #engineering Watch the first part that explains the technique of calculating the earth pre...
Rankine Active and Passive Pressures acting on a Wall: Example and Solution
Просмотров 9585 месяцев назад
The lateral earth pressure on retaining walls depends on the vertical effective stress through two coefficients: the active earth pressure coefficient (Ka) and the passive earth pressure coefficient (Kp). The Rankine theory deals with such cases, and this video explains how to apply the Rankine coefficients in a real-life case. The example is given for cohesionless soil (no cohesion) and when t...
