Abstract: The maintenance after the construction of slope reinforcing projects is always a focal and difficult point in the daily maintenance of expressways. As the new patent technologies used in slope reinforcing projects in recent years, the stress detection and compensation after the construction of anchor cables have been gradually adopted in the daily maintenance of slope reinforcing projects. The new two technologies are applied in the left-side slope of an expressway at the range of K3457+744 to K3458+144. It can be used as the reference for the similar projects in the future.
