生石灰与粉煤灰桩加固软土地基的微观分析
Microstudy on soft foundations reinforcement with lime-fly ash piles
摘要
Abstract
Presented in this paper are studies of the changes of microscopic characteristics and those of pore size distribution features before and after lime-fly ash reinforcement of the soft ground. The research methods include mercury intrusion porosimetry (MIP) test and scanning electron microscope (SEM) technique. The autors find that the extra large pores and large pores have decreased in number and small pores and micro-pores increased after lime-fly ash reinforcement. In addition,there exist different values of pore threshold for different soil deposits and the values of pore threshold radii decrease significantly after lime-fly ash reinforcement. Finally,the classified microscopic structures of different soils before and after lime reinforcement could interpret the reinforcement mechanism satisfactorily.关键词
