学科：工程地质学 词目：超固结比 英文：over-consolidation ratio，OCR 释文：超固结比又称先期固结比。为土的先期固结压力(Pc)与现有土层自重压力(Po)之比。按比值的大小，可将土固结状态分成三类：Pc/Po=1时为正常固结状态；Pc/Po>1时为超固结状态；Pc/Po<1时为欠固结状态。（历史上曾经受到过的最大固结压力P0与现在的固结压力P1的比值）

坑底以下有效桩长相同时，开挖深度越大，开挖后桩周土体超固结比越大，抗拔桩极限承载力也越大。
When the length of the pile under the bottom of the pit is the same, the deeper the excavation is, the larger the ultimate uplift capacity of pile is.
