overburden load

基本解释

This conclusion is also helpful for explaining the question that casing collapse load maybe larger than the overburden stress some times.
同时这也有助于解释套管所受外挤载荷超过上覆岩层压力的问题。
The calculation of structural load on the lining of tunnel with shallow overburden shows that the load on composite lining will be shared by primary support and secondary lining.
隧道衬砌在浅埋段的结构荷载计算表明，复合式衬砌中的初期支护和二次衬砌一般要共同承担荷载。
Therefore, we can study fault sealing through calculating the size of normal stress of fault plane, on the basis of considering overburden load and regional major compressive stress.
断层封闭性能与应力作用密切相关，可以在考虑断面受到区域构造应力与断面上覆地层负荷联合作用的基础上，通过计算断面所承受的正应力来研究断层封闭性。
