BP artificial neural networks model of design optimization of slope with anchor is established by MATLAB language and the model is trained with result of finite element as learning sample and forecast sample, the efficiency of the model is discussed, the optimal anchorage direction of slope is also established and a new way is provided for design optimization of slope with anchor.

In order to ensure the hydraulic bearing structure to press stably against the hole wall,the method to design the bearing structure and installing parameters of its hydraulic cylinders were studied.
