感谢方玉树先生对笔者拙文“考虑力矩平衡的三维剩余推力法”(以下称原文)的兴趣和讨论。方先生对刚体极限平衡法研究颇有心得,在此表示钦佩。事实上,方先生与笔者讨论的是剩余推力法和M-P法的优缺点问题,至于原文对“考虑力矩平衡的剩余推力法”采用了“条间力的方向具有较为明确合理的物理意义,又能满足力矩平衡,因而兼有剩余推力法与M-P法的优点”的评价是否恰当,或者原文是否如方先生所言“兼有剩余推力法和M-P法的缺点”等,不必辩论而自明。 Thank you Mr. Fang Yushu for my author’s article “consider the torque balance of the three-dimensional residual thrust method ” (hereinafter referred to as the original) interest and discussion. Mr. Fang expressed his admiration for the study of the rigid body limit equilibrium method. In fact, Mr. Fang and I discuss the advantages and disadvantages of the remaining thrust method and the MP method. As for the original method of “the residual thrust method that takes the moment balance into consideration”, the direction of the force between bars has a more definite and reasonable physical Meaning, but also to meet the torque balance, and thus both the remaining thrust method and the advantages of the MP method “is the appropriate evaluation, or whether the original text, as Mr. Fang said,” both residual thrust method and the shortcomings of the MP method " Do not have to debate and self-evident.
