摘要： 变形稳定标准和分级加载制度是影响K30试验效率和准确性的关键因素，与加载进程中填土的变形时间效应状态密切相关。 开展了3组最优含水率下压实系数K分别为0.90、0.95和1.00填土模型的小型平板载荷试验，获得了不同荷载作用下填土变形时程曲线和弹塑性变形数据，讨论了在K30试验加载进程中填土变形状态的变化及其对加载稳定时间的影响。

Research conclusions: The stability K30 test is better, so it is suitable to use K30 test method to test the bed coefficient of subgrade soil. However, when there is no condition to do K30 test, it is suggested to adopt standard lateral pressure penetration test, pressure-meter test and indoor test.

K30 plate loading test as a strength and deformation of indicators that are able to visually characterize subgrade stiffness and bearing capacity.

Electronic load cell and displacement sensor, equipped with PC software, easier operation, higher accuracy. USA origin oil pump and jack, more stable loading, LCD display with English language menu, with backlit. Directly display loading strength and settlement, auto calculation of K30 value and indication of pressure and settlement curve.
