passive rankine pressure
解釋
被動朗肯土壓力-
The rankine soil pressure theory is always accepted as the foundation of calculations of the soil pressure in practice. but as we know, the ignorance of the middle principal stress and the utility of mohr - coulomb strength criterion in the two - dimensional stress state make a blemish that the active soil pressure is bigger and the passive soil pressure is litter than the real
朗肯土壓力計算公式一直是工程實際土壓力計算的理論基礎，但是朗肯土壓力計算公式在推導過程中忽略了中主應力的影響，仍然應用二維應力狀態下的莫爾?庫侖強度準則，致使計算出的主動土壓力偏大而被動土壓力偏小。
