Abstract Research purposes:Based on the on-site investigation, inspection and test of the engineering quality and analysis of the information, the study is done on the main control factors o f the failure damage and failure damage type to provide the basis for test and evaluation of the anchor structure safety and engineering reinforcement.
Research conclusions:From the study , it is concluded the main control factors of the failure damage of slope anchor structure include water in fluence, unfavorable geological condition influence, vibration influence, special deformation in fluence and engineering quality influence. The engineering quality influence is the most important factor to influence the failure damage of the slope anchor structure happening or not. The failure damage types of slope prestressed anchor structure include six types, e.g. the insufficient bearing capacity of the main body of the anchor, the load on the anchor exceeding the limitation, the insufficient strength of counterforce structure, corrupt damage, disaster damage and comprehensive damage.
