摘　　要：从石油污染土再利用的角度出发,通过常规直接剪切试验,测定了不同含水率和不同原油含量、柴油含量砂土的抗剪强度,对比分析了含水量和含油量对砂土抗剪强度的影响。研究结果表明:原油和柴油的含量和油品本身的性质对非饱和砂土抗剪强度均有影响但远小于相同含量水的作用;柴油的非介电性使土明显"砂化",柴油污染砂土的抗剪强度与低含水率非饱和砂土相近;原油的润滑作用会降低污染砂土的摩擦强度。Based on reuse of oil contaminated sand, their shear strength was measured through direct shear test, the influence of water contents, crude oil contents and diesel oil contents on the shear strength of sand was comparatively analyzed. The results indicate that, oil content of sand has no marked effect on the shear strength, but the shear strength varies obviously under the same water contents. The shear strength of diesel oil contaminated sands is similar to which of unsaturated sands with low-water content. For crude oil contaminated sands, its internal friction angle declines slightly because of lubrication.
