温控路基填料变形测试仪开发设计

Development and Design of Temperature Controlled Roadbed Filler Deformation Tester

为了有效控制和评价寒区路基、路面由于冻胀和盐胀产生横纵开裂、隆起、断板等现象,影响路面使用,降低路面寿命,增加养护费用,通过开发一种温控路基填料变形测试仪可以分别模拟温度梯度和单一温度作用下寒区路基填料产生的冻胀与盐胀值。测试结果能够准确的掌握寒区土体在不同温度条件下的变形规律,从而可以对寒区路基填料在不同温度下进行变形评价分析。

In order to effectively control and evaluate the phenomenon of horizontal and vertical cracking,uplifting and broken plates caused by frost heaving and salt expansion in cold area,affecting pavement use,reducing pavement life and increasing maintenance costs,through developing a temperature-controlled roadbed filler deformation test The instrument can simulate the frost heave and salt expansion value generated by the subgrade filler in the cold region under the temperature gradient and single temperature.The test results can accurately grasp the deformation law of the soil in cold regions under different temperature conditions,so that the deformation evaluation of the roadbed filler in cold regions can be carried out at different temperatures.
