土的压缩试验中时间与荷载对土的变形量的影响

Influence of Time and Load on Soil Deformation in Soil Compression Test

摘要: 在水利工程设计与施工的过程中，要对各种水利建筑的建基面处的地质与土质情况进行严格的实验来确定它的各种性质，比如压缩性、透水性、容重、孔隙率等；有些大坝则是直接用土石料来填筑，即使是在大坝修筑完成后依然要常常监测地基或者坝体的透水及沉陷情况，因此对土的工程性质的认识提出了更高的要求。开展土力学实验——土的压缩试验为所需实验，以实验中记录的实验数据为统计量，再辅以应用统计学中的二元方差分析的知识，判断在压缩试验中时间和荷载对于土的压缩形变量的影响。从实验结果可知，对试验影响最大即最显著的是荷载因子，时间因子虽然对结果有影响但不显著。本研究结果对水利工程项目具有参考意义。

Abstract: In the process of water conservancy project design and construction, strict experiments should be carried out on the geology and soil conditions at the foundation surface of various water conservancy buildings to determine their various properties, such as compressibility, water permeability, bulk density, porosity, etc. Some dams are directly filled with earth and rock materials. Even after the completion of dam construction, the water permeability and settlement of foundation or dam body should be often monitored. Therefore, higher requirements are put forward for the understanding of soil engineering properties. The soil mechanics experiment—soil compression test is the required experiment, taking the experimental data recorded in the experiment as the statistics, supplemented by the knowledge of binary analysis of variance in statistics, to judge the influence of time and load on soil compression deformation variables in the compression test. It can be seen from the experimental results that the load factor has the greatest impact on the test, that is, the most significant is the time factor, although it has an impact on the results, it is not significant. The results of this study have reference significance for water conservancy projects.
