| 摘 要： | 分别用m法与有限元法对某抗滑桩支护工程中抗滑桩内力进行求解,结果表明沉埋法求得的抗滑阻力较小,需要进行修正。修正后,m法与有限元法计算的桩身剪力大小十分接近。但由于m法要事先假设滑坡推力分布形式,故桩身弯矩的计算结果与有限元法差异较大。建议在工程中将两种方法结合使用,可使抗滑桩设计更加安全、有效。

| Abstract: | In an engineering example,M method and Finite Element Method（FEM） were employed to calculate internal force for piles.Results show： the method based on limit equilibrium need to be modified.After correction,pile sheers calculated by two methods are similar.However,since the distribution of stabilizing force was predicated beforehand in m method,pile moments calculated by FEM are nearly 20% bigger than m method.So the combination of the two methods is recommended in pile design. |
