摘要
根据弹性力学共同变形原理,在充分考虑锚杆、浆体、岩土体协调变形状态下,得出预应力锚杆承载过程中锚杆轴力及其变形、位移的计算公式,并经104国道界河立交桥加筋土挡土墙加固工程预应力锚杆承载计算,与实测结果基本吻合,因此可以得出该计算方法是合理可靠的结论.
The formulation of bolt axis-stress and deformation according to common transmutation principle in elasticity mechanics is deduced, which is fully considered under the condition of correspond transmutation of bolt, serosity and rock. Simultaneously, the formulation is applied to analyze the results of in-situ experimentation at Jiehe intersection bridge on 104 national road, it certificated that the compute method men-tional above is credible in reason and it will be used in other engineering cases.
