天津港为适应扩大建港需要,拟延伸南北防波堤。工程要求结合大津港地区的特点尽量采用先进结构型式和材料,以达到提高建设质量、节约投资的目的。 基于天津港地区水底滩坡平缓、地基承载力低的特点,结构型式宜用斜坡堤,而砂石料缺乏,因此必须开发新的建筑材料。 用袋装粉煤灰作堤心应该是可能的,因为粉煤灰来源充足。利用土工合成材料作为外
In order to meet the need of expanding the port, Tianjin Port intends to extend the north-south breakwaters. The project requires that the advanced structural types and materials should be used in combination with the characteristics of the Dachang Port area in order to achieve the purpose of improving construction quality and saving investment. Due to the gentle bottoming of Tianjin Port area and the low bearing capacity of the foundation, the structure type is suitable for slope embankment and the aggregate is lacking, so new building materials must be developed. It should be possible to use bagged fly ash for the embankment because of the abundant source of fly ash. Utilize geosynthetics as exterior
