一、序言土的先期固结压力为土层在地质历史形成过程中所承受过的最大有效压力。研究土的先期固结压力以判定地基土属于正常固结的,超压密的或者欠压密的状态,从而正确地判定地基土的强度与稳定性以及估算建筑物或构筑物的沉降和桩基承载力。对此早已引起国内外土力学研究者与工程技术人员的重视。 测 I. Preface The pre-consolidation pressure of soil is the maximum effective pressure that the soil has undergone during the formation of geological history. Study the pre-consolidation pressure of the soil to determine that the foundation soil belongs to the normally consolidated, over-compacted or under-compacted condition to correctly determine the strength and stability of the foundation soil and to estimate the settlement and pile foundation of the building or structure Carrying capacity. This has long aroused the attention of geotechnical researchers and engineering and technical personnel at home and abroad. Measurement
