Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.
构造沉降是控制层序几何形态,充填叠置方式、演化及沉积体系分布的最重要因素:凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成;受断层控制,层序外部形态有箱状-楔形、楔形-席状披覆型,边界终止方式有双断终止型、单断终止超覆型;不同构造演化阶段层序内部充填的沉积体系各具特征,初始断陷阶段的SQ1沉积冲积层序,强烈断陷阶段的SQ2-SQ4充填湖相层序,晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积;同沉积断层陡坡带沉降迅速、可容纳空间快速增长,是凹陷的沉积和沉降中心,断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

Secondly, by the analysis of influencing factors of collapsibility of loessal foundation, results indicated that at the basis of the grey incidence analysis on influencing factors of collapsibility of loessal foundation,the void ratio is the superior and steadily influencing factor of collapsibility at all events and other influencing factors will have different degree of influence according to the specific conditions of loess foundation.
通过分析影响黄土湿陷性变形的因素,对于湿陷变形因素的关联分析,可以看出土性指标对湿陷性的影响程度,孔隙比的影响比较突出,基本上可以认为是在土性指标对湿陷性的影响程度中最大的,其它指标会因土质含量、黄土的类型不同而影响各异。总之,本文应用灰色系统理论的关联分析法对应用广泛的工程实用模型变形计算方法做一些因素分析、进行反思,同时证明了弦线模量法计算沉降是值得大力推广的,弦线模量法计算沉降在将来的工程实践中必将带来更为可观的社会经济效益。

Pacific plate subduction was dominated in study area since late Jurassic, stress regime was then transited from compression into extension associated with the steepening of subduction angel and retreat of subduction zone ocean inward; due to the difference in basement properties, extensional rifting basins dominated by depression basins developed within the Yangtze block, while volcanic faulting bounded basins for the Cathaysia block, and a series of red faulting bounded basins with half graben shape for the areas within the boundary zone between these two blocks.
晚侏罗世以后,太平洋板块对研究区的影响占主导地位,随着俯冲角度的变陡和俯冲带向洋的后撤,全区由挤压为主转变为以拉张为主的应力环境,由于基底属性有所差异,在扬子地块区域形成以拗陷盆地为主的伸展裂陷盆地,在华夏地块区域形成了火山断陷盆地,而在两大地块边界附近,则形成了一系列半地堑式的红色断陷盆地。
