The blasting effect is an important factor to influence the stability of the slope blasting construction, understanding the reasons of the slope instability under blasting construction, taking reasonable effective protective measures, which can greatly reduce slope instability phenomena during the construction. Combining with the 111 national highway (Tanghekou ~Beijing boundary) reconstruction project, through numerical simulation, using strength reduction fem for time history analysis, discuss under blast loads slope's the stress field, displacement field and the spread rule of vibration wave, systematically analysis blasting excavation impact on slope stability summarizing in construction process the question should be pay attention, which can be a guidance for relevant similar engineering design and construction.
