摘要
研究了加筋堤防软基的厚度对稳定性和变形的影响,表明:堤防软基加筋具有明显的效果;堤防软基的厚度对加筋效果有很大的影响。在软基较深时,加筋堤防稳定性趋于恒定,变形也随着深度的增加而增加;对加筋砂垫层的内摩擦角、厚度等性质进行了研究,表明:加筋砂垫层的内摩擦角和厚度对加筋的效果影响较大,在确定砂垫层的参数时,要选用较大的内摩擦角和较厚的砂垫层厚度,提高加筋效果。
The influence of the dike soft foundation thickness on the stability and deformation of the dike is studied; and the reinforcement research is carried out. Compared with the properties of the non-reinforcement soft foundation, the reinforcement results are apparent. The results show that the friction angles, and thickness of the reinforced sand layers have an important influence on the reinforcement results.
