The stability of the widening and excavation of the high slope of the expressway directly affects the safety of the reconstruction and expansion construction of the expressway.In order to ensure the safety of excavation construction,based on the principle of high slope stability,the stability of the two kinds of widening and excavation schemes of removing all support excavation and not removing the original support excavation is compared and analyzed.Finally,in combination with the actual engineering practice,the technical parameters of reinforcement measures for the slope of equal height such as the length of the anchor rod and the distance between the anchor rods are put forward.
