本文利用PLAXIS 3D有限元软件,分析了影响预应力锚索锚固体受力的几个因素,包括锚固体长度、直径、所在土层、埋置深度以及降水。计算结果表明,在相同位移量情况下水平力随着锚固体长度和直径的增加而增大;锚固体所在土层强度越大,水平力也相应越大;降水对锚固体受力影响也十分明显。
In this paper, PLAXIS 3D finite element software is used to analyze several factors affecting the stress of prestressed anchor cable anchorage, including length, diameter of anchor, soil layer, depth of embedment and precipitation. The results show that the horizontal force increases with the length and diameter of the anchor under the same displacement. The greater the strength of the soil where the anchor is located, the greater the horizontal force. The effect of precipitation on the anchoring force is also obvious .
