混合土层吹填技术对新吹填土真空预压加固效果的影响

Influence of mixed soil reclamation technology on vacuum preloading reinforcement effect of new reclaimed soil

目前的吹填施工易形成软弱土层,对新吹填土加固效果产生不良影响。根据工程实例分析,提出通过改进吹填工艺,选择混合土层吹填,紊乱土体结构,改善土体的渗透性,达到改善土体加固效果的目的,为超软基加固工程提供新的思路。

At present the reclamation construction is easy to form soft soil layers, which have a negative impact on the new reclaimed soil reinforcement effect. According to the analysis of engineering examples, we proposed that through improving reclamation process, choosing the mixed soil for reclamation, disordering the soil structure, improving the permeability of soil mass to improve the soil reinforcement effect, which can provide a new method for ultra-soft foundation reinforcement engineering.
