摘 要: | 利用数值计算探究在同一工况下,抗滑桩锚固深度分别与桩身截面尺寸、锚固段岩体强度的关系。分析结果表明:抗滑桩锚固深度随桩身截面尺寸增大而减小,但趋于一定值后,基本不再变化;锚固段岩体强度在一定范围变化时,抗滑桩锚固深度随锚固段岩体强度增大而减小,桩身弯矩呈反对称分布。

Analysis on the Anchorage Depth of Anti-slide Pile Based on Numerical Calculation |
| |
Abstract: | Using numerical calculation, the relationship between the anchorage depth of anti-slide pile and the section size of pile body and the strength of the rock mass in the same engineering condition is discussed. The analysis results show that the anti-slide pile anchorage depth decreases with the increase of pile section size, but tends to a certain value, it is not change; when the strength of anchoring rock mass change in a certain range, the anchorage depth of anti-slide pile decreases with the increase of the strength of the rock mass in the anchorage section, the bending moment of the piles is antisymmetric distribution. |
