| 英文摘要 | Carbon fiber reinforced polymer (CFRP) cable anchors, possessing exceptional mechanical properties and corrosion resistance, are increasingly serving as alternatives to traditional steel strands in coastal excavation support engineering. This study draws upon in -situ tests of deep excavation near the sea to examine the stress characteristics of CFRP cable anchors throughout their service period at various positions within the excavation plane. Moreover, the parameters of these cable anchors are optimized and analyzed through numerical simulations. The study revealed that the planar position, backfilling of the excavation and the time effect significantly affected the service performance of the CFRP cable anchors. As the days increase, the overall axial force and shear stress in the CFRP cable anchors undergo five stages of changes. Compared to steel strands, CFRP cable anchors demonstrated superior supporting effects on the adjacent soil. Given similar engineering geological conditions, the advisable range for inclination angle for CFRP cable anchors ranges between 20(degrees) and 30(degrees), and cable anchor lengths is 10% shorter than the test length up to the test length itself. Within the scope of this study, the optimal support strategy recommends a 30 inclination angle and a length that is 10% shorter than that of the test length. |
