长余高速公路稳定土强度试验研究

RESEARCH ON STABILIZED SOIL STRENGTH TESTING OF CHANG-YU FREEWAY

将长余高速公路三个路段的天然土 ,配成不同比例的石灰土和二灰土 ,并通过不同时期养生 ,对各土样进行无侧限抗压强度试验和抗拉强度试验。总结了配合比、期龄对混合料强度特性的影响规律 ,为高速公路路堤填土设计提供指南。

Three section natural soil of Chang-Yu freeway were collected as samples and mixed the natural soil with lime and flyash of different proportion, and then we made large tests of unconfined compressive strength and indirect tensile strength of stabilized soil with different curing period. We summarized the influential reqularity of strength character of stabilized soil by the mixture ratio and curing period which would provide a guide for embankment design on freeway.
