　　Bubble functions are studied herein for solving the linear elasticity problems in terms of the computational accuracy at the framework of variational multiscale method.The essence of variational multiscale method is decomposing the original problems into two fine coarse coupling problems,which are decoupled by solving the fine-scale solution with the bubble functions.

基于广义桥域法的成层土静力触探过程多尺度数值分析

静力触探试验是现场确定成层土不同土层力学性质的重要手段。静力触探过程中，探头附近区域土体的异质性行为占据主导地位，土颗粒不断滑动、滚动引起土颗粒骨架剧烈重排列、孔隙结构剧烈变化；而远离探头的剩余区域土体表现为统计均质行为。
