中文摘要：
以云罗高速公路工程中的高液限土改良方案为背景，通过试验研究颗粒级配和矿物成分对具有明显地区特征的掺砂高液限粉土和高液限黏土承载比的影响。结果表明：亲水性矿物成分是影响高液限土水敏性、膨胀率、加州承载比CCBR的主要原因之一；细颗粒含量越高，水敏性越强，ccBR越小；影响土体cCBR。的主要因素是亲水性矿物含量，其次为黏粒组颗粒曲线分布情况及黏粉比；黏粉比越小，CcBR越大。
英文摘要：
of particle Based on an improving scheme for the high-limit liquid soil along the Yunluo Expressway, the influence gradation and mineral composition on the CcBR of high-liquid limit clay and soil mixed with sand with obvious regional characteristics was studied through experiments. The results show that the water sensitivity, inflation rate, and CcBR of high-liquid limit soil were mainly affected by hydrophilie minerals; the CCBa value decreased and the water sensitivity became stronger with the increase of the fine particle content; the main influencing factor of CcBR was the content of hydrophilic minerals, followed by the distribution of clay particles and the clay-silt ratio; and the CcBR value increased with the decrease of the clay-sih ratio.
