路基設計的边坡稳定检算,工作量較大,为了提高工作效率加快设计,編制了检算用的簡化图表。由於新設規的颁佈,路基宽度变更,重新編制边坡稳定检算参考资料;今将目前适用的土質路堑边坡稳定检算参考图的编制方法介绍于下,供同志們讨论参考,以提出更好的编制方案。土质路堑边坡稳定检算参考图编制方法: (一)检算公式:K=(r∑Nf+cL+r∑T′)/r∑T=∑N/∑T f+c/r L/∑T+∑T′/∑T……(1)式中 K 稳定系数Υ土壤单位容重(T/M~2) C 土壤单位粘着力(T/M~2)
Slope stability of subgrade design, heavy workload, in order to improve work efficiency and speed up the design, the preparation of the simplified chart used in the calculation. Due to the promulgation of the new regulations and the change of subgrade width, re-compiling reference materials for slope stability check; the present compilation method of reference map of soil cut slope stability assessment is introduced below for discussion and reference Better programming. Soil cut slope stability calculation reference diagram Preparation method: (A) the formula: K = (rΣNf + cL + rΣT ’) / rΣT = ΣN / ΣT f + c / r L / ΣT + ΣT ’/ ΣT (1) where K is the coefficient of stability Υ soil unit weight (T / M ~ 2) C soil unit adhesion (T / M ~ 2)
