摘要
文章着重研究在满足库伦-摩尔条件,具有粘聚力c和内摩擦角φ两种性质的无限土体内,采用扩孔理论给出圆筒形孔二维扩张的一般解,从而得出软土地基中沉桩挤土应力场的计算公式,通过对公式的修正,寻找到便于工程实际计算的方法。
The stress field induced by pile driven in soft ground can be gotten with cylinder cavity expansion theory, it is supposed that the soil follows the Coulomb-Moore Rule. Modifications were made to the general solution of cylinder cavity expansion theory in order to apply it to the soft ground. It is important and valuable for engineers to distinguish damage risks caused by pile driven in engineering practice.
