| 摘 要： | 预应力锚索框架是加固边坡、滑坡常用的方法。目前框架梁的设计方法以Winkler弹性地基梁理论为主，其理论的基本假定与地基土体的实际性质有较大差别，计算结果偏于安全。文内引入Vlazov双参数地基模型，推导了框架梁内力计算公式。两个算例的对比分析表明，利用该法在保证加固效果的同时，可在一定程度上降低工程造价。

| Abstract: | Prestressed anchor cable frame is the common method for slope and landslide reinforcement.At present,frame beam design is mainly based on the theory of Winkler elastic foundation beam,but the basic assumption of this theory is largely different from the actual nature of foundation soil mass,so the calculation result deviates from safety.This paper introduces Vlazov two-parameter foundation model to educe the formula of inner force of frame beam.Compared to these two results,it is found that the latter method may reduce engineering cost to a certain extent as well as ensure reinforcement effect. |
