Abstract : based on the rigid visco-plastic fem technique, this paper numerically simulate the superplastic bulging process of void-sensitive materials using pressure controlling strategy of maintaining maximum effective strain rate constant and void damage evolution model of superplastic forming 文摘:基于刚粘塑性有限元技术采用最大应变速率恒定的压力控制策略和超塑性成形空洞损伤演变模型对空洞敏感材料的超塑性胀形过程进行了数值模拟。
Based on the theory of unsaturated soil mechanics and the properties of compacted expansive soil, this paper takes the northern part k12 + 840-k12 + 920 of nanning urban highway as an example to studies some aspects of lime improvement of expansive soil and the technology of construction . the chief content of this paper is : the lime improvement mechanism of expansive soil; confirm the technical parameters of lime mixed from the results of test in laboratory; the scale-down test to define the maximum effective grain size of expansive soil when it is improved by lime; by building bank slope model and making use of finite element seepage flow program of saturated-unsaturated to calculate the examples, this paper simulates the humidity site in order to checkout the effect of lime improvement; studies and proves that it is feasible to mix blocky expansive soil and pulverous lime, and to fill roadbed by common construction machines etc . 本文研究的工作就下述几个方面展开:用石灰改良膨胀土的机理;通过室内试验确定掺灰的技术指标;在室内进行膨胀土掺灰的最大有效粒径的模拟试验,即钙离子水试验,由此总结出“粉?块”灰?土搅拌工艺的有效性、合理性和可行性;用数值方法对路堤使用期的湿度场进行模拟,并与路堤的强度?变形的计算域耦合,以检验土性改良的效果,从而探索一种描述改良膨胀土路堤运行工况的数值方法;用现有最常用的且费用最低的施工机具,对灰?土进行“粉?块”搅拌掺和及路基的填筑施工等。
