Abstract：There are two opinions of using finishing rolling steel anchor and prestressed steel strand cables in landslide supporting-retaining structure. One considers that finishing rolling steel anchor has higher anticorrosive performance and longer serviceable life than those of prestressed steel strand cable，while the other thinks that prestressed steel strand cable is more convenient because of its advantages of technical maturity，covenant construction and low cost，although the prestressed steel strand cable is prone to corrosion failure under the condition of long-term immersion of water in reservoir. The performance and the price of finishing rolling steel bolt and prestressed steel strand cable are compared by field experiments. The results provide useful data for the utilization of finishing rolling steel bolt and prestressed steel strand cable in geological hazards treatment.
