A road engineer is looking for ways to improve safety on a stretch of road bordered by a moderately steep field of small boulders. Suggest and describe three techniques that could be used practically
What will be an ideal response?
ANSWER: A successful answer will include three of the following:
- The engineer could use heavy-duty metallic fencing or netting to hold the bottom part of the slope in place.
- A barrier of high-strength concrete or “shotcrete” could restrain the boulders more effectively.
- If the conditions are right, rockbolts could be used to anchor the deep part of the slope to the barrier in front.
- It may be worthwhile to see if water in the slope is increasing the danger and provide drainage.
