| 摘 要： | 在土工离心模型试验中,模型材料的几何尺寸应为原型材料几何尺寸的1/n。然而在很多试验研究中,由于缩尺制备的原因,很难满足这一要求。基于土工离心模型相似原理,对其结构物的替代准则进行详尽的综述、分析和讨论,为工程应用提供参考依据。

| Abstract: | In geotechnical engineering eccentric model test,the geometric dimension of model material shall be 1/n the geometric dimension of prototype material.However,this requirement is very hard to meet due to reduced scale preparation in many test studies.Based on the principle of similitude among the geotechnical engineering eccentric models,this paper summarizes,analyzes and discusses in detail the substituting rule for structures,providing reference basis for application in projects. |

| Keywords: | eccentric model test reduced scale structure substituting rule |
