天津新港地区软土层较深,土质较差,—13米(本文高程除图7、图8以新港理论深度基准面为准外,其于均以大沽零点为准)以上土层的含水量平均为50%左右,个别土层高达60%～70%,渗透性低,压缩性高,力学指标一般都较低。所以,码头大都设计成高桩承台结构形式。岸坡型式基本上分为两类:一类是岸坡的部分土压力由桩来承受,没有桩的支撑,岸坡自身不能稳定。例如,一港池顺岸码 Tianjin Xingang area soft soil layer deeper, poor soil quality, -13 meters (this elevation except Figure 7, Figure 8 to Newport theoretical depth reference surface, which are based on the Dagu zero) above the soil containing The average amount of water is about 50%, individual soil layers are as high as 60% -70%, low permeability, high compressibility and generally low mechanical indexes. Therefore, most of the pier design into a high-pile cap structure. There are basically two types of bank slope: one is that part of the bank slope is under the soil pressure and the pile itself is not supported by the pile, and the slope itself can not be stabilized. For example, a port cistern code
