The direct calculation formulas of the rectangular foundation containing weak underlyingstratum are induced and a computer program is developed.
推导出具有软弱下卧层土矩形基础的直接计算公式，编制了相应的计算机程序。
2
When there is weak underlyingstratum bellowed the soil which is not be reinforced, the weak underlyingstratum should be taken checking computations.
当桩端未加固土层以下有软弱下卧层时，应对其进行软弱下卧层验算；
3
The stress field of the reinforced area and the underlyingstratum was calculated and the distribution characteristics of the additional stress field of DJMP...
