中文摘要：
研究部分地锚式斜拉桥受力特点及其合理成桥状态的确定原则，提出一种二阶段合理成桥状态下的索力确定方法．该方法采用刚性支承连续梁法确定成桥状态下的索力，并以影响矩阵法进行后续调整．根据该桥型受力特点制定了第2阶段的索力调整流程，对一座主跨1218m的混合梁部分地锚斜拉桥进行了计算．结果表明，按照第2阶段索力调整流程可较快确定出合理成桥状态下的索力．
英文摘要：
Based on the mechanical characteristics of partially earth-anchored cable-stayed bndge,the criterion oi reasonable completed status is put forth. A two-stage method is presented. It is by means of the method to determine the cable force of traditional self-anchored cable-stayed bridges in reasonable completed status. The initial cable force of partially earth-anchored cable-stayed bridge is calculated by rigid supported continuous beam method. Then the final optimized cable force in the reasonable completed status is obtained by influence matrix method. The adjustment process of the cable force in secondary stage is on the basis of the mechanical characteristics of partially earth-anchored cable-stayed bridge. The result for the partially eartk-anchored cable-stayed bridge with 1 218 m main span and composite beam shows that the cable force in the reasonable completed status of bridges can be obtained faster according to the adjustment process of cable force in secondary stage.
