本课题面向复杂荷载环境,以滨海软弱土的损伤机制和评价为研究目标,以静、动力作用下的软弱土损伤机理研究为主线,开展滨海软弱土原位性状评价方法、复杂荷载环境下滨海软弱土损伤机制等基础研究,揭示滨海软土的沉积环境与原位性状相关性,提出滨海软弱土工程性状评价与智能识别方法,获得复杂荷载作用下滨海软弱土损伤机制与本构表征,建立反映宏微观特征的软土多尺度损伤本构关系。将软弱土灾变的经验性认识拓展到面向动力学过程的机理认识,实现静力与动力相结合、微观机制研究与宏观力学分析相结合、内在机理与本构模型相结合,为滨海软弱土损伤诱发灾变机制研究提供工程性质参数及本构模型。 This subject takes the damage mechanism and evaluation of coastal soft soil under complex load environment as the research object.This study carries out basic research on in-situ property evaluation method of coastal soft soil,damage mechanism of coastal soft soil under complex load environment,the correlation between depositional environment and in-situ property of coastal soft soil,and also puts forward the damage mechanism of coastal soft soil.The damage mechanism and constitutive characterization of coastal soft soil under complex loads are obtained by the method of engineering properties evaluation and intelligent identification of soft soil,and the multi-scale damage constitutive relationship of soft soil reflecting macro and micro characteristics is established.This study also expands the empirical knowledge of soft soil catastrophe to dynamic process-oriented mechanism knowledge,realizes the combination of static and dynamic,micro-mechanism research and macro-mechanics analysis,internal mechanism and constitutive model,provides engineering parameters and constitutive model for the study of damage-induced catastrophe mechanism of coastal soft soil.
