Which of the following engineering controls would be best suited to strengthen a slope that has been over-steepened by cutting into the hillside during highway construction?

Question

Quizplus · Accepted Answer

Building a retaining wall is the best engineering control to strengthen a slope that has been over-steepened by cutting into the hillside during highway construction. A retaining wall provides added support to the slope and prevents it from sliding or collapsing. Rock bolts and controlling the flow of water can also provide stability, but they may not be as effective as a retaining wall in this particular situation. Covering the slope with vegetation and building a tunnel do not provide any reinforcement to the slope.
