摘　　要：针对道路路基承受柔性荷载的特点,考虑桩顶刺入变形,结合采用弹性力学中Mindlin法与Boussinesq法联合求解半刚性桩复合地基及下卧层土中应力与沉降。工程实例计算表明,本方法所得到结果与实测结果有较好的一致性。For analyzing the additional stress and settlement of half-rigidity piles composite foundation, the new method, using the Mindlin and Boussinesq solutions with the characteristic of roadway bearing flexible load and piles piercing into foundation considered, is presented. The calculation for a project problem shows that the calculation results using the above method have good agreement with the project test results.
