Interpretive Geological Cross-Section - Foundations and Stability - Engineering Assignment Help

Assignment Task :

LNG Site Assignment
In this assignment you will assess the ground conditions of your cross-section based on three drill holes including: foundation and slope stability conditions, excavatability and potential for construction material. In addition to lithology (rock type) there is a log of the strength and RQD in the drill holes. Be aware there are many gaps in the strength and RQD data record. In most cases you can assume the value to be zero if it is not provided.

Background: The project data is typical of the site preparation of a major LNG facility.
Part 1 – Interpretive Geological Cross-section
Using the same methods as given in Assignment 1A (Melbourne Interpretive Geological Cross-section) complete a cross-section for the three drill holes allocated to you from the NWLNG database. The drill holes are 50 m apart and should be presented in order of lowest number on the left side of the crosssection. Use a vertical exaggeration of 10. Present the cross-section in the same format as required  

Part 2 – Foundations and Stability
You will make an assessment of the geological conditions that would be encountered in the base and cut slopes of a trench excavation. You will not actually design a foundation or undertake design calculations.
Scenario: The site requires excavation to a depth of 5 m above sea level. The excavation is centred on your middle drill hole. The base of the trench excavation is 15 m wide. The cut slopes at each side of the trench can be 2:1 or 3:1 (H:V). The steeper slope would be recommended if the slope is mainly in sound rock and the shallower slope would be recommended if the slope is mainly in soil or unsound rock.

The slopes can be stabilised temporarily against erosion by placing hard rock fragments against any soft rock or soil exposed on the slope. Mark the location of these stabilisation works on your cross-section graphic.
Instructions: On a copy of your cross-section graphic from part 1, illustrate the trench excavation floor and show the recommended slopes for the sides of the trench.
