萧振群同志在其“调整连续梁桁架内部应力之研究”一文中证明两跨连续梁最有利的应力调整的绳准是在离端支承x=0.707l处的最大正负弯矩相等。讨论者们通过简易的数学运算,推广解决多种超静定桥梁应力调整绳准点的位置: 对于三跨连续梁桥,边跨的绳准点的位置在距端支承x≈0.775l处,中跨的绳准点在各距支承x≈0.3l处; 对于多跨连续梁桥,中间各跨的绳准点的位置在距支承x≈0.25l处; 对于两铰拱,绳准点的位置在x≈0.3l处,其推力的最有利调整值为:H_o=M_++M_-/2y,式中M_+、M_-、y等为绳准点处的最大正核心弯矩、最大负核心弯矩、相对铰轴连线的座标; 对于无铰拱,绳准点的位置在x≈0.25l处。
Comrade Xiao Zhenqun proved in his article “Research on Internal Stress of Continuous Beam Truss” that the most favorable stress adjustment criterion for two-span continuous beams is equal to the maximum positive and negative moments at the end support x = 0.707l. Through simple mathematical operations, the discussants promoted the solution of the quasi-point positions of various types of statically indeterminate bridge stress adjustment ropes. For the three-span continuous beam bridge, the position of the quasi-point of the side span was x≈0.775l at the end support, Of the rope punctuation at the distance from the support x ≈ 0.3l at; for multi-span continuous beam bridge, the middle of the cross-punctate rope position away from the support x ≈ 0.25l; for the two hinge arch, rope punctuality position in x ≈ 0.3 l, the thrust of the most favorable adjustment is: H_o = M _ + + M _- / 2y, where M _ +, M _-, y and so on for the rope punctuality of the maximum positive core bending moment, the maximum negative core bending moment, the relative Hinge axis connection coordinates; for the hinge-free arch, rope punctuality position at x ≈ 0.25l at.
