目的:在对土体固结问题进行求解时,如果对孔压和位移采用等阶积分,当时间步长取值很小时,得到的孔压结果会出现数值振荡,导致精度降低。本文提出一种非等阶积分的求积元孔压单元,致力于减小孔压振荡,提高单元稳定性和计算精度。创新点:1.建立了一种对于孔压和位移采用不同阶积分的求积元复合单元;2.有效降低了小时间步长引起的孔压振荡。方法:1.通过求积元法对弱形式控制方程进行数值积分,并对比奥固结方程中的位移项和孔压项采用不等阶积分;2.通过拉格朗日插值获得位移点上的孔压和孔压点上的位移值;3.通过一维及二维问题的数值算例,验证所建立方法的有效性。结论:1.通过采用复合求积元单元,大大降低了孔压的数值振荡;2.应用复合求积单元时,采用二阶精度的Crank-Nicolson积分格式不会产生随时间的孔压振荡;3.本文所建立的单元可以大大提高固结问题求解的数值计算精度和计算效率。

目的:考虑几何非线性及非达西渗流对软粘土固结的影响,提出一种大变形固结问题的求积元求解列式,以提高数值方法的计算精度及计算效率。通过数值算例研究几何非线性及非线性渗流定律对软粘土固结的影响,为工程实际提供参考。创新点:1.提出一种大变形固结问题的高阶数值求解方法;2.在固结问题求解中同时考虑几何非线性及非线性渗流定律。方法:1.基于初始构型,采用完全拉格朗日格式,建立大变形固结问题求解列式;2.基于变形梯度乘法分解,得到大变形条件下的土体本构模型;3.基于指数关系的渗流定律,建立渗流连续性方程;4.通过数值算例验证方法,研究几何非线性及非达西渗流对软粘土固结的影响。结论:1.所建立的求积元方法的收敛速度要远远快于有限元法,降低了问题计算规模;2.在小变形条件下,最终沉降随外荷载线性变化,而在大变形条件下,随着载荷的增大,沉降相对于小变形条件有所降低;3.当考虑非达西渗流定律时,软粘土的固结速率随着非达西渗流参数的增加而降低。

全面抗击疫情中的两个场景令人印象深刻:一是有一位年轻人躺在方舱医院的病床上捧书阅读;二是师生卷入居家学习的热潮。这两个场景提出了一些值得我们思考的问题:学生毕业离校后,是否还有学习动能?学生离开课堂(如寒暑假、特殊时期),学习是否“熄火”?学生是否具备了理性应对社会风险、反思自我发展的学习素养?这为我们探讨如何将学习素养纳入人才培养目标与教育改革内容提供了契机。

高等教育普及化对大学生学习素养提出了新要求。大学生学习素养是大学生在接受高等教育阶段所养成的适应学习需要且能迁移至未来社会生活的能力和品质,具有持久性、可迁移性和集成性。当前我国大学教学存在片面的教师中心、浅表性学习、功利化教学等问题,严重制约了大学生学习素养的养成。大学教学改革要重视提高大学生学习素养,重视为不教而教、为培养大学生的创新素养而教、为大学生的终身发展而教,培养时代所需要的高素质专门人才。
