| 摘 要： | 在预应力锚索加固边坡工程中,对于锚墩加框架梁受力体系的分析,目前还未见有效的计算模式。通过对实际工程中锚墩与框架梁在张拉时的位移监测数据进行分析,探讨锚墩与框架梁的共同作用机理,得出了锚墩在外锚固体系中的分担作用。同时计算出框架梁在锚索作用下的位移曲线,与实测数据进行对比分析,表明该计算模式具有较好的效果,有实际应用价值。最后根据对锚墩位移监测数据的统计,对不同地质条件下的地基反力系数的取值范围进行了探讨,供工程应用中参考。

| Abstract: | There is still no effective model for analysis of frame beams with anchor pier, which is widely used in slope reinforcement engineering. Based on the field-measured displacement data, the interaction between frame beams and anchor pier is studied and corresponding formulation is presented. The validity and the practicability of the formulation are verified by the good coincidence between the computational displacement with measured displacement of the frame beams. Suggestions for span of the coefficient of the subgrade reaction are also presented based on the statistics of the measured anchor pier displacement data. |
