To find out thoroughly the reasons of slope ' s unstability , earth stress has been measured at slope by means of technique of temperature compensation and automatic recording
测量应用采用完全温度补偿技术和自动化记录系统的空心包体应变计进行，得出了该地区地应力分布的基本规律。
In the finite element consolidation analysis , the large strain calculation of volumn strain will appear in the continuous equation , this will make it very complex and inefficient when execute the fem calculation . this paper compares the differences among three kinds of volumn strain calculation method and points out that the small strain method can be utilized in the fem program , which is perfectly acceptable in large scale , and can simplify the calculation and promote the efficiency
在大变形固结有限元分析时，需要在连续方程中引入大变形的体应变度量，但精确的体变度量表述使得方程的形式非常复杂难以进行有效计算分析。本文对体应变的不同描述方法作了对比分析，结果表明在大变形有限元分析中引入小变形的体应变度量方法在很大范围内是理想的，并可以简化计算过程，提高计算效率。
