通过对CFRP钢管混凝土桩基试件进行锈蚀试验和轴向受压承载试验,系统分析CFRP钢管混凝土桩基在腐蚀前后荷载-位移曲线、极限承载力的变化规律,重点研究材料的基本性质和劣化程度对极限承载力的影响。试验结果表明,CFRP材料能够显著改善普通钢管混凝土桩基的受力特性,进而有效提高桩基的极限承载力。
- Abstract:
-
By conducting corrosion tests and axial compression bearing tests on CFRP steel tube concrete pile foundation specimens, the changes in load displacement curves and ultimate bearing capacity of CFRP steel tube concrete pile foundation before and after corrosion were systematically analyzed, with a focus on studying the influence of material properties and deterioration degree on ultimate bearing capacity. The experimental results show that CFRP material can significantly improve the stress characteristics of ordinary steel concrete pile foundations, thereby effectively increasing the ultimate bearing capacity of pile foundations.
