So centrifuge model test technique can be used to forecast consolidation and seepage condition of prototype 因此,利用离心模型技术可以预测原型的固结情况和渗流情况。
At last, this thesis points out some problems existing in the centrifuge model test technique and estimates the developing trend of this technique 论文最后指出了离心模型试验技术目前存在的一些问题和今后的发展趋势和研究方向。
Centrifuge model test technique preferably solves two problems : one is the gravity loss of the model soil, the other is the coupling problem between the seepage field of the ground water and the stress field of the stratum, which is a guidance for other deformation controls under the similar condition 离心模型试验技术较好的解决了在地下工程研究中模型土体的自重损失和地层位移分析中地下水渗流场和地层应力场相互耦合作用问题,对于在相似条件下富水地层隧道开挖施工如何控制地表沉降变形的研究方面具有指导意义。
Geotechnic centrifuge model test technique utilizes the equivalence between centrifugal force field and gravitational field; model dimension dwindles into 1 / n times of prototype " s, but the body force on the model increases n times . the strain and stress of model is equal to prototype " s, but the displacement of prototype is n times of model " s 土工离心模型试验技术利用离心力场和重力场等效性,将模型尺寸缩小到原型尺寸的1/n,同时作用在模型上的体积力增大n倍,这时,模型中各点的应力、应变与原型中对应点的应力、应变相等,原型和模型对应点的位移成n倍关系。
