摘要:
对锚杆格构梁进行了系统的模型试验研究，探讨锚杆格构梁的受力特点及规律．模型试验在坡体后缘加载，通过在格 构梁上布置压力盒及应变片得出了格构梁底部土体压力及变形的分布．结果显示，随着荷载的增大，格构梁所受压力及应变随之增大，在格构梁悬臂端及跨中所受压力较小、变形较大，在格构梁交叉处所受压力较大、变形较小，格构梁整体压力及应变基本呈三角形分布．
Abstract:
This paper discussed the stress characteristics and rules about anchor lattice beam based on the scientific indoor model test. This test has load on the tailing edge of the slope, get the press and strain distribution of the bottom soil of the lattice beam by the pressure cell and strain gauge put on the lattice beam. The result shows that with the increase of load pressure, the press and strain on the lattice beam increases, but the press on the cantilever end and mid-span of the lattice beam became diminished and the strain increased. On the other hand, the press on the cross of the lattice beam became greater and the strain became diminished. Overall the press and strain distribution on the lattice beam oresent to be of a triangle type.
