Anchor reinforcement is one of the most effective measures on geotechnical engineering of strengthening field, which is applied to the field of foundation pit bracing, tunnel support, dam overturning resistance, slope slip resistance and so on. The strengthening effect relates with the properties of injected paste. Generally, the higher of mortar labeling, the higher strengthening of the bolt, and the shorter of the bolt needed. That is possible to satisfy the need of special construction. Therefore, the research on grip between bolt and mortar has important realistic meanings.Study on the changing characteristics in power of gripping, according to strength grade between cement mortar, curing age, block size and different shape bolt, and summarize the change law. On this basis, engineering design and cost are analyzed, which are combined with engineering example. Hence, conclusions are obtained as follows:1. The influence law of site effect, the number of needling, curing age, mortar strength grade is studied by mortar pouring experiment and drawing experiment. While the failure mode of plate type bolts in each factor is explored, obtained optimal combination of the plate-resistant anchor by experiment data.2. Numerical simulation is applied to simulate the experiment to verify the correctness of the model. The failure mode of plate type bolts in each factor is explored by simulation. Contrasting with the experiment data, it can be transpired that the simulation result is basically correct.3. The342profile of BUZHAOBA is reinforced by bolt and plate-resistant anchor, while feasibility and effect of the two methods are studied by numerical simulation, which embodies the superiority of small dosage, longer distance and so on.4. The cost analysis of slope reinforcement is made by Gloden to contrast the two methods, and reveals the considerable economic of plate-resistant anchor reinforcement method, while it plays good reinforcement effect.
