饱和土二维固结试验在离心力场条件下的适用性分析
The Applicability of Two-dimensional Consolidation Test of Saturated Soil in Centrifugal Force Filed
摘要
Abstract
Geotechnical centrifugal model test similar to the best performance in various types of geotechnical physical model test. Because of the test conditions, centrifugal model test is used to be one-dimensional consolidation test. In fact, lateral drainage of ground will accelerate the dissipation of excess hydrostatic pressure and affect the consolidation settlement. In order to study more practical features of saturated soil consolidation in the two-dimensional drainage conditions centrifuge model test, the centrifuge model box is transformation designed. Typical causes of saturated soil in different areas under the two-dimensional drainage conditions of centrifugal consolidation tests are studied. It is indicated that, in the centrifugal consolidation force filed conditions, the consolidation characteristics of saturated soil with smaller consolidation coefficient was closer to two-dimensional consolidation theory. Geotechnical centrifuge model test can provide foundation conditions for a two-dimensional consolidation test of saturated soil.关键词
