滩地粘质粉土充袋技术在黄骅地区的应用试验

Technique of Filling Bag of Shoal Clayey Silt Applied and Tested in Huanghua Area

本研究设计在沧州黄骅港某临时隔堤工程中进行室内试验。研究主要发现,滩地可用砂源分布极为不均匀,经常移泵,滩地取砂效率极低。研究采用滩地粘质粉土充袋技术完成隔堤的施工工作,其对充灌潮次、总固结时间影响不大,只是对充灌历时、单位时间方量有影响,可较好的适应附近的自然条件,对类似工程在该地区的推广应用有借鉴作用。

The laboratory test was carried out in the design of the temporary separation levee project of Cangzhou Huanghua port.The research results show extremely uneven distribution of available sand sources.The pump was often moved,which caused very low efficiency of sand extraction.In the research,the bags filled with shoal clayey silt were applied in the construction of separation levee,which had little influence on the filling tide and total consolidation time,except for the influence on the filling duration and the filling volume per unit time.The above technique could adapt to the surrounding natural conditions well,and served as a reference for the promotion and application of similar works in this area.
