高边坡支护与锚索锚固参数优化研究
Study on Parameter Optimization of High Slope Support and Anchor Cable Anchorage
【摘要】 基于莫尔-库仑屈服准则和强度折减法理论,运用Midas GTS软件对云南省红河州绿春县高级中学高边坡与坡顶建筑物稳定性进行研究,确定了桩锚支护下边坡安全系数为1.37。通过正交试验对预应力锚索锚固参数进行优化设计,以提高边坡安全性,减小坡顶建筑物桩基位移。综合分析得到最优锚固参数为锚杆入射角度20°,锚杆间距2.5m,锚索预应力500kN。
【Abstract】 Based on the Mohr-Coulomb yield criterion and the theory of strength reduction method, Midas GTS software is used to study the stability of high slope and slope top buildings in Lüchun County Senior Middle School, Hani-Yi Autonomous Prefecture of Honghe, Yunnan Province, and the safety factor of the slope under pile-anchor support is 1.37. The anchoring parameters of prestressed anchor cables are optimized by orthogonal test, which can improve the safety of the slope and reduce the pile foundation displacement of slope top buildings. Through comprehensive analysis, when the incident angle of the bolt is 20°, the distance between the bolts is 2.5 m, and the prestress of the anchor cable is 500 kN, the anchoring effect is best.
