%X <p id="p00010">To more accurately investigate the anchorage mechanism of pressure cables,in consideration of plane stress conditions,we derived the approximate theoretical solutions for both the compressive stress of the grouting body of pressure anchor cable and the shear stress between anchor solid and rock-soil layer based on Mindlin’s fundamental solution. Through example analysis,we revealed an inverse relationship between the anchorage angle and the stress distribution curve of the grouting body, as well as a power function relationship between the anchorage angle and the peak stress of the grouting body in the anchoring section. The anchorage angle significantly influences both the compressive stress of the grouting body at the anchoring section and the shear stress at the interface between anchor solid and rock-soil layer. These findings not only enrich the understanding of the pressure cable anchorage mechanism but also provide valuable references for the development and application of new anchoring technologies. Additionally,they offer theoretical support for the design of pressure anchor cables in rock and soil engineering.</p>
