เข้าร่วมเมื่อ 12 มิ.ย. 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
มุมมอง 33016 ชั่วโมงที่ผ่านมา
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
มุมมอง 178วันที่ผ่านมา
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
มุมมอง 3762 หลายเดือนก่อน
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
มุมมอง 6753 หลายเดือนก่อน
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...

Sir, i want to ask at the last minute of this video, the equation of k20 = k x kt. Where did you get the value of k ? Based on 3 average of data or what ?
very obviously🎉

Sir please upload the video for toe erosion analysi
Many landslides occur when surface water drains into a large crack on the surface of the hillside. All this water saturates the ground at the bottom of the crack and then all the weight of the earth above sinks or slips in the mud. Surface drainage culverts, landscaping and regular watering can help keep a hillside stable.

Hi sir i need joint number count formula in per meter cube for RQD calculations means you explained joint spacing formula but i need joint count number formula Thank you
I wonder how the thickness of the layers does not affect the calculations. In fact, if I do the spt test with more repetitions in the adjacent layers, the liquefaction potential index will increase.

I just wanted to ask. When you say, "When we change the water flow, we also change the level in manometers," how do I do this? How do I change the level of the manometers? Thank you!

Great video! Note: In the normalization calculation (N1,60), you forgot to divide by 60% (or 0.60). The N1,60 should be 34.8, not 20.4. Please check.
