【摘要】 以均匀设计、有限差分理论为基础,建立了土层锚杆、土钉主要设计参数的分析方法。按照均匀设计的要求,选取不同的设计参数;通过应用于土木及采矿工程的拉格朗日元法的应用程序FLAC3d,结合工程实例,对土层锚杆、土钉进行均匀数值模拟,初步探讨了设计参数对基坑变形的影响,可供超近(深)基坑复合支护结构变形控制设计时参考。更多还原

【Abstract】 The new analysis method of main design parameters of soiled nail was established by uniform design,calculus of differences in this paper.According to uniform design,different design parameters were chosen.By using the Fast Lagrangian Analysis of Continua,the uniform numerical simulation experiments are performed.The influences of soil nailing parameters to support deformation have been discussed,which is useful when the soil nailing designs of ultra near deep foundation pits is based deformation-controlled.更多还原
