safety load factor

基本解释

The 3 times safety factor of the recommended load to the test load ensures optimal working conditions.
推荐负载安全系数为3，确保最佳的工作条件。
Load capacity contained by calculating safety factor that resistant to fatigue damage caused by the maximum load force.
负载能力通过计算抵抗最大负载力造成的疲劳毁损的安全系数得出。
When the distance of pile and tunnel Within the critical distance, load of pile has greatly influence on safety factor of tunnel. when the load increases twice, safety factor will reduce about 1/4.
隧洞围岩岩体强度对围岩安全系数影响较大，本文围岩强度从砂岩降低至泥岩时，围岩的安全系数降低1/4。
