土工一般的模型试验是在比原型小得多的自重应力状态下进行的,土体的应力,应变的相似条件常常难以满足,试验结果往往不理想。 土工离心模型试验是把土工结构的模型放在高速旋转的离心机中进行的,由于离心力的作用,使得模型达到和原型相同的应力水平,满足相似条件。这项试验技术早在30 The geotechnical general model test is carried out under self-weight stress much smaller than the prototype. The similar conditions of soil stress and strain are often difficult to meet, and the test results are often not ideal. The geotechnical centrifuge model test is carried out by placing the model of the geotechnical structure in a centrifuge rotating at a high speed. Due to the centrifugal force, the model reaches the same stress level as the prototype to satisfy similar conditions. This test technique is as early as 30
