湖北地区老黏性土自然条件下具有超固结、高强度、低压缩性、整体性好、较高的抗剪强度和凝聚力等物理力学特性，同时也具有一定膨胀性和微裂隙性。老黏性土开挖卸荷、浸泡、干裂等外界条件改变后，其强度将急剧衰减，老黏性土“软化”对工程建设影响十分巨大。本文通过工程勘察过程中老黏性土遇水“软化”的试验结果，初步分析老黏性土遇水“软化”后的衰减情况。

Under natural conditions, the old cohesive soil in Hubei Province has physical and mechanical properties of ultra-consolidation, high strength, low compression, good integrity, high shear strength and cohesion, but also has some expansibility and micro-fissures. After excavation unloading, soaking and drying shake, the external conditions of old cohesive soil have changed, its intensity will rapidly decay, so the old cohesive soil"softening"has great impact on the construction. By the test results after old cohesive soil"softening"in engineering investigation process, this paper made a preliminary analysis of intensity attenuation situation of after old cohesive soil"softening".
