| 摘 要： | 目前边坡工程中锚固参数的确定多以经验和规范为主,各参数之间的匹配不尽合理。正交设计作为处理多因素试验的一种科学的试验方法,只要少次数的试验就可判断出较优的试验条件,若再对试验结果进行统计分析,还可以更全面、更系统的掌握试验结果,做出试验因素对评价指标的正确判断。运用正交设计方法对京珠高速公路大悟段某边坡锚固参数进行了优化设计,优化结果表明以边坡水平变形量为评价指标,主要锚固参数对错固效果的影响显著性依次为:锚杆长度＞锚杆间距＞混凝土喷层厚度,得出的最优参数方案为锚杆长度3.0m、锚杆间距2.0m、混凝土喷层厚度100mm。

| Abstract: | The parameters of anchoring bolt are very important for anchoring effects. Orthogonal optimum design is an effective method for anchoring bolt. Anchoring parameters of slope of Dawu section in Jingzhu high way are selected using orthogonal design principle. The results show that the effects of anchoring parameters are different and remarkable according to horizontal deformation of slope. The order of the difference is: the effect of anchoring bolt length the interval of anchoring bolt thickness of sprayed concrete. The optimum parameters, i.e. it's the length of the anchoring of 3 m, the interval of the anchoring of 2 m and the thickness of concrete of 100 mm, are obtained. |
