On the basis of stability analysis, the author takes the K27+825 slope from the type of slope which has lest stability as an example. According to its basic feature, the design ueses the choosed best reinforce and control scheme: lattice beam, anchor wire, grouting and abstraction of water. In the course of design, the author takes into account not only reasonable optimize of whole control plan but also local measure such as whether the unstable block will shear from vnlnerable sections when control plan is laid out concretely, in order to reach the goal of reasonable design and effective control.
