design safety factor meaning in Chinese
设计安全系数
Examples
- It was shown that the measured active soil pressures were smaller than the theoretical values and diminished with time , the measured pore water pressure decreased with the time and increased with the depth of soil , the combinative effects of cap girder and supporting structure were obvious which diminished the displacement of foundation pits , and the measured axial force of the anchor and interior steel beam were far less than the design force , indicating that the design safety factor of the foundation pit was too large to be economical
基坑工程实行信息化施工并获得了丰富的监测数据，通过对数据分析结果表明：实测主动土压力小于计算主动土压力，实测主动土压力随时间延长变小：土体中孔隙水压力随时间增长而减小，孔隙水压力随深度增加而呈非线性增加；基坑冠梁协同作用明显，冠梁减小了基坑变形；锚索轴力比较稳定，钢撑轴力变化相对较大，且二者轴力仍富余较大，该设计比较安全。 - 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
本文在研究碾压混凝土重力坝渐进破坏过程和可能失稳方式的基础上，提出了以准弹性临界作为稳定临界准则的设计极限状态，分析了按该准则设计的大坝的实际工作状态，导出了以准弹性强度储备系数为设计安全指标的审查公式以及形式与抗剪断公式相同的简化公式，探讨了定量计算考虑各种因素影响的相应设计安全系数的合理取值，并与现行规范方法进行了比较
