袋装固化土筑堤在沿海涂面整理工程中的应用

受制于砂石等建筑材料匮乏,浙江沿海围垦工程推进困难,寻找合适的替代材料迫在眉睫。因地制宜,就地取材,利用滩涂丰富的黏土资源,形成袋装固化土筑堤技术。即利用滩涂淤泥为原料,添加固化剂充灌袋体作为堤心代替砂石料等常规材料修建围堤。通过对固化土工程特性和袋装固化土围堤在外部荷载作用下的稳定情况进行研究,结合台州已建固化土围堤的经验和试验及检测资料,提出合理的计算方法,为固化土筑堤设计方法的建立提供可靠的依据。

Application of bagged solidified soil in the coastal reclamation project

Because of the shortage of construction materials,such as sand and gravel,it is hard to pursue the coastal reclamation project in Zhejiang,so it is very urgent to find a suitable alternative material.According to the local conditions,using the local materials,we study the application of the rich muddy resource on the intertidal zone,format a technology using bagged solidified soil to build embankment,which uses the mud on the intertidal zone for construction material instead of sand and gravel,with curing agent to fill bags as the embankment core to build embankment.Through the study of the engineering properties of solidified soil and stability of paged solidified soil dike under external load,combined with the built solidified soil dike experience,test and inspection data in Taizhou,put forward a reasonable calculation method to provide a reliable basis for design method of building embankment using solidified soil.
