充填管袋填筑的原理与实践

Principal of mud-filled bag embankment and practice

阐述了充填管袋填筑的基本原理,包括充泥管袋的固结理论、管袋在波浪及水流作用下的稳定性理论。从国外和国内不同的充泥管袋型式,各自得出一些理论计算公式,并应用于实践。固结理论考虑充泥管袋固结过程中含水率的变化,结合单向固结理论,计算出充泥管袋高度的变化,进而得到平均固结度;采用静力平衡理论,对充泥管袋的稳定性进行理论分析,进而得到满足稳定的特征值,并得出一些结论。

This paper briefly presents the fundamental principle of mud-filled bag embankment, including consolidation theory of mud-filled bag, the stability theory of mud-filled bag under the condition of wave and current action. According to different mud-filled bag pattern at home and abroad, some theoretical computation formulas were respectively obtained and used in practice. In consolidation theory, water content rate variation of mud-filled bag in the process of consolidation is considered, and in combination of uni-dimensional consolidation theory, the height variation of mud-filled bag is computed and mean consolidation degree is obtained. Adopting static equilibrium theory, the theoretical analysis of mud-filled bag stability is carried out and some characteristic values to meet stability requirement are obtained. Some conclusions are given in this paper.
