摘要
针对黄土路堤强夯压实处理问题开展了模型试验研究。基于几何相似、运动相似及动力学相似原理设计模型路基及夯击功能,在路基中布设了加速度计及分层沉降标。按路基土不同的初始干密度及路顶单点夯和多点夯情况进行了强夯压实试验,研究了模型路基在强夯前后的分层压实度变化规律、路顶分层土的夯沉量和侧向挤出变形量以及强夯振动力沿路基深度水平向的传递规律,为强夯压实黄土路堤技术的工程应用提供参考依据。
The model of embracement and tamping energy were determined based on the principle of geodetic, the cinematic tamping energy are determined based on the principle of geodetic,kinematic and dynamics similarity. The accelerometer and laminar settlement mark were fixed in embankment. According to the different initial dry density, the tamping test was tanked by the way of singlepoint and multiplepoint in top surface of sugared. The principle of the degree of compaction change,the settlement of embankment, lateral deformation and tamping strength delivery along level correction of subgrade were presented.
