| 摘 要： | 文章根据地基反力呈抛物线分布的假设,在临界接触,局部接触和全面接触的三种情况下,推导了由于开采影响,地面出现负曲率变形,建筑物产生的附加弯矩和附加剪力.结果表明,正负曲率变形的计算公式和临界半径值均是不同的,但在全面接触条件下,最终的弯矩和剪力当正负曲率值相同时,其结果绝对值相同符号相反.

| Abstract: | The formulas of the maximum bending moment and the shearing force were devided based on the supposition of parabolic distribution for the resistance of building and structural fundation.
When the concave curvature deformation occure onthe surface above mining area, refer to the three cases of critical, full, and partial contact between the foundation and the earth. |
