The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.
条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统,本文分别对它们的形成与发育、地貌特点及动态变化进行了分析,并探讨了影响其发育的主要因素,即来水条件、来沙条件、空间条件,划定了其主要发育阶段,即形成期、成熟期、衰亡期;在上述分析的基础上确定了潮盆—潮沟系统的主要功能,即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态;同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

The scale-value, which is converted from the bore-hole strain, by nse of the observed values in tidal frequency band of the bore-hole strain and the elastic coefficients of the bore-hole corescan can be used for coverting non-tidal variation of the bore-hole strain into variation of the non-tidal stress of the same stratum.
顾梦林 ,杨毅,骆鸣津利用钻孔应变观测值中潮汐频段部分和钻孔岩芯的弹性系数,将钻孔应变换算为地层应力的格值,用此格值可将钻孔应变的非潮汐变化换算成该地地层的非潮汐应力变化。

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.
峡道深水区沉积是指水深大于30米的峡道底部沉积,它以粗颗粒砂砾石沉积为特色,是现代峡道水动力对第四纪海退时发育的冲洪积和坡积物进行改造形成的蚀余沉积,全新世沉积地层往往缺失;峡道过渡带沉积是指水深介于低潮位线至30米水深线之间发育的峡道边坡沉积,该带沉积以沉积物类型多样为特色,自低潮位线至30米水深线,沉积物粒级逐渐变粗,由粉砂质粘土逐渐递变为中粗砂,是峡道深水区沉积物经多次分选沉积而发育的,基本平行于等深线分布的条带状沉积,在岸坡较陡岸段,过渡带下部可发育重力沉积;峡道潮滩沉积是指在低潮线与海岸线之间发育的细颗粒沉积,它是粘性细颗粒泥沙在潮滩动力作用下,发生动水絮凝沉积而形成的粉砂质粘土沉积,在低潮滩可发育浮泥;峡道口门区沉积则是在峡道汇入大海或海湾时,在峡道出口水流影响所及范围的沉积,根据峡道口门区供给泥沙的特性,峡道口门区沉积有粉砂质淤泥沉积和砂质沉积两种类型。
