我院材料结构室研制的六米离心机是用于光弹和土工试验的大型试验设备。在1983年下半年机电系统基本调试成功后,又进行了大量的光弹试验的调试工作。在取得了满意的结果后,于1985年1～3月先后进行了三次难度较大的三维水工光弹模型试验:其中一个模型是具有三个机窝的薄壁结构模型,做了模化比为90的自重试验;另一个是尺寸为长390毫米,高320毫米的复杂地基厂房模型,连同加载夹具总尺寸为长520毫米,高385毫米,总重量为重3公斤,分别作了自重模化比为100,外水压力模化比为53的两次试验,上述三个试验均为
The six-meter centrifuge developed in our material structure room is a large-scale test equipment for photoelastic and geotechnical experiments. After the basic commissioning of the electromechanical system was successful in the second half of 1983, a large number of photoelastic tests were commissioned. After satisfactory results were obtained, three difficult 3D hydro-optic model tests were conducted successively from January to March 1985: One of the models was a thin wall structure model with three sockets. The 90-yard self-weight test; the other is a complex ground-based factory model measuring 390 mm in length and 320 mm in height. The total size of the load fixture is 520 mm in length, 385 mm in height, and 3 kg in total weight. The two tests with a mode ratio of 100 and an external water pressure moderation ratio of 53 are all three tests.
