建立可靠的地层年代标尺对于研究滨海地区晚新生代沉积物记录的沉积环境变化、新构造运动及古气候演化具有重要意义。对位于天津滨海地区迄今所获得的最长的全取心钻孔G2(深1226m)进行了详细的磁性地层学研究,在此基础上探讨了该孔年代地层划分及其区域构造意义。结果表明,G2孔的底界年龄约为8.5Ma。其中,1226~658m为晚中新世,属馆陶组上部,658~303m属上新世明化镇组,303m以上属第四纪马棚口组、佟楼组、塘沽组和天津组,全新统天津组底界深度为19.4m。G2孔包含2个沉积速率较高(大于200m/Ma)的时期,分别为8.5~6.43Ma和3.58~3.03Ma。这2个时期与晚中新世以来青藏高原的扩展隆升在时间上有很好的可比性,指示高原隆升可能对华北地区的沉积和构造演化有重要影响。
It is of great importance to establish reliable chronologic framework in Binhai area for understanding the late Cenozoic depositional environment change, neotectonic movement and evolution history of paleoenvironment. In this paper, the authors pres-ent the magneto-stratigraphic investigation result in drill hole G2 (1226m), which is the longest drill hole in the Tianjin coastal area. On such a basis, the chronostratigraphic subdivision and its tectonic significance were also discussed. The results show that the core of this drill hole began deposition at about 8.5Ma BP. The strata of 1226~658m may be correlated to late Miocene and assigned to upper member of Guantao Formation, the strata of 658~303m belong to Pliocene Minghuazhen Formation, and the upper strata of more than 300m belong to Quaternary, including Mapengkou, Tonglou, Tanggu and Tianjin formations. The basal lower boundary of Ho-locene is identified at about 19.4m by 14C dating. Given the chronostratigraphic scal

在室内三轴蠕变试验的基础上,分析了天津滨海地区重塑饱和软黏土的非线性蠕变特性。蠕变试验采用分级加载的方式进行,利用"陈氏法"对实测数据进行处理,得到饱和软黏土在不同应力状态下的蠕变试验曲线。在此基础上,依据黏土的应力-应变、应变-时间关系,分别用Singh-Mitchell和Mesri经验模型拟合试验数据。总结拟合结果,结合滨海软黏土的蠕变特性,提出一种分段拟合的Mesri模型,在蠕变前期,模型的应力-应变关系采用双曲线函数,应变-时间关系采用幂函数;在蠕变后期,模型的应力-应变关系采用双曲线函数,应变-时间关系采用双曲线函数,以两条拟合曲线的交点作为分段拟合的分界点。对比分析表明,该方法能更好地描述具有衰减稳定特性的蠕变曲线。选取天津滨海地区原状土蠕变试验数据对该模型进行验证,拟合结果较好,由此建立了适用于具有衰减稳定蠕变特性的滨海软黏土非线性蠕变模型。
Based on the indoor triaxial creep tests, the nonlinear creep properties of the remoulded saturated soft clay in coastal area of Tianjin were analyzed. The creep tests were carried out by the step loading method, and the creep curves of the soft clay under different stress states were got by processing the measured data by Mr. Chen′s method. In addition, Singh-Mitchell model and Mesri model were respectively used to fit the test curves which are the stress-strain isochronal curves and strain-time curves. Combining with the fitting results and the creep proper-ties of the coastal clay, a piecewise fitting Mesri model was put forward. In the early stage of the creep, the hyperbol-ic function was taken to describe the stress-strain relationship, and the power function was used to describe the strain-time relationship. In the late stage of the creep, two different kinds of hyperbolic functions were respectively used to matching the stress-strain relationship and the strain-time

天津滨海地区地处渤海湾西岸,晚新生代沉积了巨厚的松散沉积物。地下水位下降、地层自然固结、地表载荷的加速增长等复合因素造成了严重的地面沉降。利用在天津滨海新区塘沽地区施工的一眼1 226 m全取芯钻孔,通过原状样品测试分析,系统研究了晚新生代土层的物理力学性质、黏性土固结特征,并结合欠固结黏性土层沉降量计算等方法阐述了土层固结状态空间特征,探讨了土层固结特征与地面沉降的相关关系。结果表明:该地区0~100 m深度土层具有低天然密度、高孔隙比、高含水率、高压缩性等特点,表现出软土的性质,在地表荷载增大的情况下,易发生地面沉降;100~550 m的黏性土大都处于超固结和微超固结状态,主要是由于过去地下水的大量开采造成的;550 m以下的黏性土多为正常固结,局部存在欠固结黏性土夹层。钻孔中存在合计约218 m的欠固结黏性土夹层,这些欠固结黏性土夹层在自重应力下的最终沉降量为1 985 mm,沉降量最大的土层对应于第1、6含水组,分别达614 mm和665 mm,这一沉降过程完成所需时间为数十年甚至上百年。
Tianjin coastal area (TCA), located at the coastal region on the west of the Bohai Gulf, has suffered severe land subsidence due to compaction of the huge thick unconsolidated sediments deposited since Late Cenozoic era. Several factors, including groundwater level decline, clayey soils natural consolidation and surface loading rapid increase are the primary causes of land subsidence in this region. A borehole with depth of 1 226 m is drilled at Tanggu in the TCA;and core samples are extracted at various depths. Through laboratory test of these undisturbed soil samples, the physical and mechanicanl properties and the engineering geological properties of all kinds of clayey soils are analyzed. Integrating estimation of total compaction of the under-consolidated clayey soils, the spatial characteristics of natural consolidation of the unconsolidated sediment layers are delineated;and the relation between consolidation characteristics and land subsidence is discussed. The results indicate

Large-scale sand bags are used to be core of dikes in Tianjin Binhai Area. In general,the subgrade soil is consolidated by laying horizontal sand bedding and inserting vertical plastic drains. The sand-bag dike core on the exposed side is protected by rubble bedding and armor gratings. The settlement of dike will be observed during the construction. One dike settlement observation example is adopted to analyze the cause for the difference between the design settlement value and the observed data. Meanwhile,suggestions are brought forward for laying and embedding the settlement measuring points.
