摘要
推导了基于Mohr-Coulomb屈服准则的非线性土力学模型,利用MSC/NASTRAN软件对冲击式压实机非圆柱形压实轮压实效果进行了有限元计算分析。计算结果与试验结果对比表明,计算结果满足工程精度要求,可以替代试验作为衡量压实效果的手段。并模拟计算了两种不同外形压实轮的压实效果,对影响压实效果的因素进行了分析。
The non-linear soil mechanics model based on Mohr-Coulomb yield criteria is deducted, and impaction effect of non-column wheels of compacting roller is calculated using MSC/NASTRAN. The comparison between calculation and experimentation indicates that the calculation satisfied the engineering precision and it can replace experimentation to measure the compaction effect. In the meantime, the compact effect of two kinds of wheel is simlated and several factors are discussed.
