Prestressed anchorage is a very effective method to supervise high slope stability. By studying the simulation of various existing prestressed anchor, the paper works up a reasonable model and uses ANSYS for numerical simulation. With the example of the high rock slope of a hydropower project, the paper uses the limit equilibrium method to analysis slope stability and evaluates prestressed cable (pole)...
Uncertainty is one of the major inherent difficulties for R&D, especially for innovative R&D projects. The objective of this paper is to develop a flexible decision making methodology based on the real option concept to improve development flexibility for R&D projects. The proposed methodology identifies potential risks that may occur during R&D, recognizes a cascading option structure...
In this paper, we first conduct a detailed analysis of special equipment safety, and then on this basis, we propose countermeasures: develop and implement the safety production responsibility system, the periodic inspection system, uphold the system of certificates, correct use, careful maintenance. Finally, we use “electricity loss protection system of elevator” as an example to explain.
