【摘要】 土钉支护已广泛应用于边坡工程,但至今对土钉支护参数的选取尚无规范可依。基于有限差分法软件FLAC,利用正交试验设计进行数值模拟,得到一定坡高土钉支护参数的合理取值范围,并选取典型工点对土钉的支护效果进行稳定性评价,对比处治前后边坡的安全系数及最大水平位移,结果表明,在正交试验基础上选取合理的土钉支护参数,边坡的稳定性大大提高。计算结果可为土钉支护定量化设计提供参考。更多还原

【Abstract】 Soil nailing has been widely used in slope engineering,but so far there are no norms that the soil nailing parameter selection can conform to.Based on the finite difference method FLAC software,orthogonal design for numerical simulation is used to get a reasonable range of soil nailing parameters under a certain slope height,and the example of typical soil nailing is selected to evaluate the supporting effect,and then the slope safety coefficient and the largest horizontal displacement before and after treatment are compared.The test results show that slope stability has been greatly increased by selecting the reasonable supporting parameters of soil nailing based on the orthogonal test.The results of soil nailing can be used as references for quantitative design of soil nailing.更多还原
