yield factor of safety
解釋
屈服安全系數-
On the basis of investigations into the progressive yield process and the possible failure modes of rcc gravity dams, the quasi - elasticity design limit state of the ctrtical stability criterion is proposed and the real working state of the dams designed according to the ctriterion is discussed. a check formula using the material strength reducing factor as the safety index and a simplified formula similar to against sliding stability fromula are derived. finally, the corresponding design safety factors are given by using fem calculations with various influence parameters to be taken into account
本文在研究碾壓混凝土重力壩漸進破壞過程和可能失穩方式的基礎上,提出了以準彈性臨界作為穩定臨界準則的設計極限狀態,分析了按該準則設計的大壩的實際工作狀態,導出了以準彈性強度儲備系數為設計安全指標的審查公式以及形式與抗剪斷公式相同的簡化公式,探討了定量計算考慮各種因素影響的相應設計安全系數的合理取值,並與現行規范方法進行了比較 -
At the same time, several yield criterions are studied in order to find the best one. on the base of above, a rational safety factor of slope is calculated with shear strength reduction technique
第三,在彈性數值流形元的基礎上,考慮了土體彈塑性的應力?應變關系,研製了彈塑性流形單元分析程序。
