本项目拟针对川西山区河谷及沟谷斜坡下部或坡脚下部位的崩坡积典型混合土,依据非饱和土力学的有关理论,利用土水曲线压力板仪量测该混合土的土水特征曲线,配合土动三轴试验机研究循环荷载作用下该混合土在不同土性-初始受力-动应力组合条件下的非饱和动变形特性,探索各因素的影响机理,为崩坡积混合土岩土工程在不同气候、水文条件下的建设、稳定性分析与震害防治提供可靠的理论依据。
According to the theory of unsaturated soil mechanics, the soil-water characteristic curve of the mixed soil is measured by the soil-water curve pressure plate meter, and the slope- With the soil moving triaxial testing machine, the unsaturated dynamic deformation characteristics of the soil under cyclic loading under different soil-initial stress-dynamic stress combinations were studied, and the influence mechanism of each factor was explored. Soil engineering in different climate and hydrological conditions of the construction, stability analysis and prevention and treatment of damage provide a reliable theoretical basis.
