| 摘 要： | 利用改进的湿化试验装置对取样子陕南西部的几种膨胀土进行了湿化试验，研究表明，试前含水量和裂隙发育状况对膨胀土在静水中的崩解有重要影响，膨胀土的湿化过程可分为吸不增重阶段，崩解缓慢加速阶段，崩解剧烈发生阶段和崩解减慢一终止阶段，膨胀土经过重塑后其湿化性主要受试前含水量和干密度控制。

| Abstract: | Using improved trial equipment of disintegration, experiments on several expansive soils obtained from South Shanxi Province were done. The researches showed that pretest water content in soil specimen and growth condition of crack had an important effect on disintegration of expansive soil. The process of disintegration was divided into four phases: soil sample water absorption and its weight increase phase, disintegration slowly accelerating phase, disintegration violently taking place phase, disintegration slowdown and final stage. After remolding expansive soil disintegration characteristics were controlled by pretest water content in soil sample and dry density of soil. |
