摘要:
土工离心模型试验技术是各类土工物理模型试验中相似性能最好的模型试验,由于试验条件限制,通常认为其进行的都是一维单面排水固结试验,而实际工程中,地基的侧向排水会加速超静水压力的消散,对其固结沉降有较大影响.为了探索更接近于实际情况的土体固结特性,及其在二维排水条件下饱和土的离心模型固结特点,基于离心机模型箱的改造设计,对典型区域饱和土体的二维固结特性进行了离心模型试验研究及其试验结果的对比分析.结果表明,在离心力场条件下,固结系数对土体的试验结果影响较大,固结系数较小的饱和土样二维固结试验特性更接近于理论；土工离心模型试验具有饱和土二维固结特性研究的基础条件.
Abstract:
Gused to be one-dimensional con-solidation test. In fact,lateral drainage of ground will accelerate the dissipation of excess hydrostatic pressureand affect the consolidation settlement. In order to study more practical features of saturated soil consolidationin the two-dimensional drainage conditions centrifuge model test,the centrifuge model box is transformationdesigned. Typical causes of saturated soil in different areas under the two-dimensional drainage conditions ofcentrifugal consolidation tests are studied. It is indicated that,in the centrifugal consolidation force filed con-ditions,the consolidation characteristics of saturated soil with smaller consolidation coefficient was closer totwo-dimensional consolidation theory.Ceotechnical centrifuge model test can provide foundation conditions fora two-dimensional consolidation test of saturated soil.
