摘　　要：A technology is widely used in the construction of highways and bridges in China, which is prestressing technology. Whether this technology is used properly will directly affect the quality of the entire project. The optimal control application of prestressing technology can reduce costs and improve Engineering benefits. The application of prestressing technology in China started late, but it has achieved rapid development. The construction of prestressing technology needs to control many key links such as technical inspection, concrete pouring construction, steel strand installation and construction, and tensioning construction. Pay attention to tensioning problems, corrugated pipe clogging problems, grouting problems, construction quality problems, etc., from the reasonable selection of steel strands and stress anchors, the scientific treatment of tendon threading , construction, and the selection of reasonable tension construction, etc. The maximum utility of prestressing technology in highway bridges ensures the safety and stability of highway bridges.
