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. Key words : anchorage; post construction; stress detection; stress compensation 0 引 言 本文以某高速公路 K3457+744—K3458+144 段左 由于岩土锚固工程结构的复杂性，预应力锚索结
