强度包线 meaning in English

mohr’s envelope

The strength line of consolidation undrained shear of field soft clay is polygonal . on the basis of the character , and the calculation formula of stability and strength increase of structural soft clay ground can be obtained
原状结构性软土的固结不排水强度包线为折线型，根据此特征给出了考虑结构性影响的预压地基的强度增长和稳定安全系数计算公式。
Based on the summary of the famous strength criterions or strength envelope models in last century , smp ( matsuoka - nakai ) strength criterion which is wildly used in soil mechanics is briefly introduced and then brought into the practical calculations in geotechnical engineering in this paper , namely this famous three - dimensional strength criterion is used to modify the classic rankine soil pressure theory and the formulas of the critical edge load and the critical load
本文在综述了上世纪一些著名的破坏准则和强度包线模型的基础上，简单介绍了在土力学中有广泛应用的smp (松岗?中井)破坏准则，将这一著名的土体三维破坏准则应用于岩土工程实际计算(土压力计算和地基承载力计算)中，即运用smp (松岗?中井)破坏准则修正了经典的朗肯土压力计算公式和临塑荷载、临界荷载计算公式。
